In a recent Facebook live video stream, while Zuck smoked meats on his backyard grill and answered questions from the audience, the social networking CEO fielded a fair volley from viewer on the topic of Musk's concerns for the future. Musk has historically been very vocal about his concerns to tread carefully with AI as it becomes more powerful, especially if it were to end up in the wrong hands.

This viewer asked for Zuckerberg's stance on the dangers of AI, to which he responded, "I have pretty strong opinions on this. I'm really optimistic. I'm an optimistic person in general. I think you can build things and the world gets better. With AI especially, I'm really optimistic, and I think that people who are naysayers and try to drum up these doomsday scenarios ... I don't understand it. It's really negative, and in some ways, I actually think it's pretty irresponsible."

Calling Elon Musk "irresponsible" sounds like a rather bold and brash thing to say about a guy that's building premium all-electric cars, engineering sustainable energy solutions and making space payload delivery runs while landing rockets back on earth, where historically they were nothing more than disposable multi-million dollar junk after one use. If you consider Musk's considerable knowledge-base in AI, especially with Tesla's research and development in self-driving cars, Zuckerberg's comments definitely sound like shots fired.

Young Zuck went on to note how AI would help make cars safer in the future and literally save lives, which is ironic since Musk too has envisioned a future where self-driving cars would eventually be much safer than humans and he's been rather vocal about that too. What Musk is really concerned with though, are scenarios when AI is forced to make real-world, split-second decisions, about which human lives or dies, for example. This is just one of the many realities that are coming and humans are going to be responsible for regulating and programming that AI to act accurately, carefully, morally and lawfully.

The vote was as narrow as it gets: With two Republicans out of their slim majority of 52 opposing Majority Leader Mitch McConnell’s motion to proceed on Tuesday afternoon, Vice President Mike Pence broke a 50-50 tie to formally launch deliberations that had taken place almost entirely in private for two months. The vote was briefly delayed as Senate officials removed protesters shouting “Kill the Bill! Kill the Bill!” from the balcony of the chamber.

As recently as 24 hours before the vote, Senate aides were predicting it would fail, delivering yet another blow to the GOP’s hopes of at least partially repealing and replacing Obamacare after seven years of campaign promises. But the return of Senator John McCain of Arizona after a brain-cancer diagnosis and McConnell’s success in wooing his fellow Kentucky hardliner, Senator Rand Paul, gave the motion some late momentum. In a dramatic moment, McCain entered the chamber long after most Republicans had voted to cast a crucial vote to begin debate. But even with McCain’s support, McConnell still had to persuade Senator Ron Johnson of Wisconsin, who has criticized his handling of the issue, to vote with the party. After a lengthy one-on-one discussion with the majority leader, Johnson cast the 50th vote after McCain had entered the chamber to a round of bipartisan applause.

All 48 Democrats protested the move by initially abstaining from the vote before they all voted no. Senators Susan Collins of Maine and Lisa Murkowski of Alaska were the only two Republicans to oppose the motion.

In a statement, Trump hailed Senate Republicans “for taking a giant step to end the Obamacare nightmare.” And during a press conference soon after, he suggested that the initial procedural vote would prove to be more difficult than the ones that followed. But McConnell and his fellow Senate leaders knew the opposite was likely true.

Countless nails have been hammered in Flash's coffin in recent years, most notably by Apple's Steve Jobs and also by Adobe itself. Now, though, there's a date for the funeral: Dec. 31, 2020.

Flash has been a website workhorse -- online gaming site Kongregate has more than 100,000 Flash games -- but don't fret over the demise of the pioneering software. It's more appropriate to rejoice, since the software today is a security risk and major source of browser crashes.

"I am glad Adobe is ending Flash's life. It has honestly made the web a worse place for more than a decade," said Creative Strategies analyst Ben Bajarin.

Indeed, Adobe's move is momentous enough that the biggest names in web tech -- Apple, Google, Facebook, Mozilla and Microsoft -- coordinated announcements to tell us what's going on and to reassure us all that it's going to be fine.

What's it mean for me?

For the time being, you'll have to jump through some hoops to play Crush the Castle. In the coming months, depending on what browser you use and how it's configured, the Flash phase-out could be anything between no biggie and a serious problem. Some games will stop working. Schools and businesses that rely on Flash-based instruction modules will have to move into the future. Some websites, especially old ones that are no longer updated, might stop working.

Today's workarounds all will break on mainstream browsers by the end of 2020. Here's a rundown of what you can expect:

Chrome: Google's browser began asking us for permission to run Flash on some websites last year, and it'll do so more often and later disable Flash by default. "We will remove Flash completely from Chrome toward the end of 2020," Google said.

Firefox: Mozilla's browser will start asking you in August which sites you want to enable Flash on, it'll disable Flash altogether by default in 2019, and there will be lingering support through the end of 2020 only in Firefox's less frequently updated Extended Support Release. ...

Microsoft signaled an about-face in a blog post Monday night by Megan Saunders, a general manager within the Windows Experiences group. Instead of deprecating Paint in Windows 10 (which seemed to many to be the first step toward oblivion), Saunders said Microsoft would release MS Paint in the Windows Store as a free app. "MS Paint is here to stay, it will just have a new home soon, in the Windows Store where it will be available for free," Saunders wrote.

Saunders acknowledged the pleas of Paint fans who didn't want this longtime app to go away. "Today, we’ve seen an incredible outpouring of support and nostalgia around MS Paint," Saunders wrote. Her next words were almost sentimental, as she affirmed Paint's continuing existence: "If there’s anything we learned, it’s that after 32 years, MS Paint has a lot of fans. It’s been amazing to see so much love for our trusty old app."

Microsoft had previously classified the Paint app as “deprecated” within the upcoming Windows 10 Fall Creators Update, meaning Microsoft would officially cease development on it, and it could be removed from the OS either with the release of the FCU or in the future. Microsoft apparently still plans to remove it—yet allow users access to it if they so choose.

Saunders didn’t say when Paint would be transitioned over to a Store app, nor did she mention whether it would still be developed--or just preserved in amber. Saunders did say that Paint3D, Microsoft's new 3D content creation app, will remain and receive updates in the future.

Paint was born with Windows 1.0 in 1985, as a licensed version of ZSoft’s PC Paintbrush. Microsoft updated Paint over subsequent versions, adding support for JPEG, TIFF, and other file formats. Though far more sophisticated imaging tools have risen around it, Paint always served as a quick-and-dirty photo editor and drawing tool.

Pushed by China and its increasingly tough emission rules, the company reluctantly committed to building all-electric cars by 2020.

Now a report suggests that the company's electric-car ambitions are increasing.

The Chunichi Shimbun, a Japanese newspaper, reports (via Reuters) Toyota is developing solid-state batteries for its future electric cars.

The first vehicles to house that next-generation technology, it says, will go on sale early in 2022.

That's likely right around the time that a fifth-generation Prius would be released, potentially offering Toyota opportunities for joint development of its new electric car alongside its iconic hybrid.

Late last year, Japan’s Nikkei newspaper said Toyota would build and sell its first long-range electric car by 2020.

The importance of the effort may be indicated by reports that namesake and CEO Akio Toyoda would head the team developing the new electric model.

Every battery company is now investing major funds in both lithium-ion cell advances and research into next-generation technologies.

If the reports are accurate, Toyota's use of solid-state cells could conceivably be a first for any large global carmaker.

Claims that the upcoming Fisker Emotion luxury electric sedan would use a graphene-based battery were superseded by reality this week, as the company announced it had parted ways with the startup company Nanotech, which was to supply the cells.

According to the report from Chunichi Shimbun, Toyota’s solid-state batteries will offer greater range than current lithium-ion batteries and, crucially, a recharge time of only a few minutes.

As the name suggests, solid-state battery cells use a solid electrolyte rather than the liquid used in most lithium-ion cells today.

The claimed benefit of solid-state batteries is that they're less prone to overheating or fire, and their energy density is much higher, meaning longer-range electric cars with smaller, lighter battery packs.

Today, however, solid-state cells remain extremely expensive to fabricate on a mass scale. That's the arena in which dozens of companies are collectively pouring billions of dollars of research and development funding.

Toyota began research on its hydrogen fuel-cell technology at the same time it launched the Prius hybrid team in the early 1990s.

Its Mirai, now on sale globally for more than two years, has struggled to win sales amid a slower-than-expected rollout of the hydrogen fueling-station network required to operate the cars.

For now, there’s no detail beyond that. Apple declined to comment to the Journal and hasn’t responded to our own request for comment.

If Trump’s statement is correct, that’d be a big investment on Apple’s behalf and a significant change of pace. Right now, Apple only has Mac Pros manufactured in the US, and it hasn’t even committed to continuing that. Apple also generally prefers to work with outside suppliers, so it can source parts from multiple companies and shield itself from risk — such as when it turns out that an entire factory is worthless because its manufacturing method didn’t pan out.

That’s why it seems quite possible that Trump has some of the details wrong here. For instance, Cook may have said that Apple’s suppliers are building new factories in the US, rather than Apple itself. Apple recently invested $200 million in Corning, which supplies cover glass for iPhones, with the intention of supporting the company’s manufacturing efforts, already located in Kentucky. Foxconn, a major Apple supplier, is also said to be planning its first US factory. That factory may well produce products for Apple, though it wouldn’t be an Apple-owned factory.

If so, it doesn’t seem like Trump cares about the distinction, as long as he can say Apple is becoming more involved in US manufacturing. “I said you know, Tim, unless you start building your plants in this country, I won’t consider my administration an economic success,” Trump told the Journal. “He called me, and he said they are going forward.”

This has been a sticking point for Trump for a long time. On the campaign trail, he repeatedly called out Apple for its reliance on foreign manufacturing. “I'm going to get Apple to start making their computers and their iPhones on our land, not in China,” he said during a speech last March. “How does it help us when they make it in China?”

And since the election, Trump has spoken in increasingly optimistic terms about the potential for Apple to build in the US. Trump said he spoke with Cook about it shortly after the election, and then just before being sworn in, said that Cook had his “eyes open to it.” ...

A survey of surveys, the report brought together over 185 studies conducted between 1973 and 2011, creating a compendium of tests of 43,000 males. By highlighting results from “Western” countries — including New Zealand, Australia and other developed nations with strong European heritages — researchers found that sperm counts fell from 99 million per ml in 1973 to 47.1 million per ml in 2011 within the relevant age cohort. That’s a decline of 52.4 percent or 1.4 percent every year.

Most interestingly, this precipitous decline was not found in non-Western nations or the developing world — though the authors acknowledged that lack of robust and broad testing in those areas may have skewed their results.

It’s a dramatic finding that highlights an ongoing trend that researchers and fertility experts have amplified repeatedly over the last generation. While some, as the Guardian notes, have claimed that such sharp declines are due to technological advancements and new techniques in testing, the authors of the Human Reproduction Update report said that they had factored in those changes.

While there are no true answers for what may be causing such a dramatic decline (if it exists), multiple experts have theorized that poor health trends in developed countries may be a factor. Decreased physical inactivity, increased BMIs (Body Mass Indexes) and stress, as well as exposure to a myriad of artificial and natural compounds in both the environment and food have been sighted as likely culprits. Yet, there is no substantial body of evidence that could cement any of those real-world lifestyle changes as true, scientific factors in the overall drop in sperm counts.

Sexual transmission of HIV is negligible when someone is on treatment, whether they're in a heterosexual or homosexual relationship, according to results from previous studies and now a large-scale study of homosexual men, presented at the ninth International AIDS Conference on HIV Science in Paris on Tuesday.

HIV experts emphasized this aspect of prevention, highlighting the "Undetectable equals Untransmissible" campaign, during a press conference at the international meeting. The campaign works to encourage people worldwide to stay on treatment by ensuring they understand that doing so could mean they cannot infect others.

This message is not aligned with the status quo in terms of the care people infected with HIV receive today, believes Bruce Richman, founder and executive director of Prevention Access Campaign and the "Undetectable = Untransmittable" initiative. "This is transmission-stopping information," he said.

New vaccine results have shown promise at the meeting this week and in recent studies, but are still far from becoming a reality to end the epidemic.

Overwhelming evidence

In the largest-ever trial on HIV transmission risk among homosexual men, Australian researchers explored the sex lives and HIV rates of more than 350 homosexual couples where one person is HIV positive. The couples were from Brazil, Thailand and Australia.

Each couple reported their sexual activity when visiting clinics involved in the trial and HIV-negative partners were regularly tested to diagnose any new infections.

The couples participating reported having sex almost 17,000 times without condoms between them over four years, and none of those times resulted in new infections.

"There was not a single linked HIV infection in these couples," said Andrew Grulich, professor of epidemiology at the University of New South Wales in Australia, who led the study. "Nobody became infected from their partner."

Three new infections were discovered during the trial, but analysis of the virus showed they had come from sex outside of the relationships, not from the person on treatment within the couple.

Sex without a condom is not necessarily advised, however, to prevent risk of other sexually transmitted infections (STIs). "This (group) had very high STIs," Grulich told CNN, adding that 20% of the men in the trial developed STIs each year, yet there were zero HIV infections.

"I said, who the hell wants to speak about politics when I'm in front of the Boy Scouts?" Trump said.

Trump went on to dive into politics anyway -- blasting the media, pushing for the repeal of Obamacare and making a pointed remark about "loyalty."

Listing off the virtues of Boy Scouts at the West Virginia speech, Trump said: "As the scout law says, a scout is trustworthy, loyal," Trump said, before adding, "We could use some more loyalty, I will tell you that."

Trump's comments came the same day he called Attorney General Jeff Sessions, who was in the Boy Scouts, "beleaguered" in a tweet expressing his frustration over the ongoing Russia investigations.

At the event, Trump also warmly recalled his victory against Hillary Clinton in the presidential election.

"Do you remember that famous night on television, November 8?" Trump asked.

He told the Scouts that Republicans had a tremendous disadvantage in the Electoral College and that the popular vote, which he lost to Clinton, "is much easier." He went on to tell the Scouts his victory was "an unbelievable tribute to you and all of the other millions and millions of people that came out and voted for Make America Great Again."

The Boy Scouts of America issued a statement in response to Trump's appearance on Monday, clarifying that the Scouts did not endorse Trump nor did the group support a particular "position, product, service, political candidate or philosophy," and that the group simply always extends invitations to sitting presidents.

It concluded, "the sitting US president serves as the BSA's honorary president. It is our longstanding custom to invite the US president to the National Jamboree."

Trump said many of his advisers were Boy Scouts, as were 10 of his Cabinet members. "Can you believe that? 10," Trump said.

Two of those former Boy Scouts and now-Cabinet members, Interior Secretary Ryan Zinke and Energy Secretary Rick Perry, joined Trump onstage. Secretary of State Rex Tillerson, who made it to Eagle Scout and was the group's president from 2010-2012, addressed the jamboree Friday.

Trump said several times the media would downplay the size of the audience at the Summit Bechtel Family National Scout Reserve, which the Boy Scouts in a news release prior to the event said they anticipated would be more than 40,000 people.

Goodbye Microsoft Paint

It’s the end of an era. Microsoft has added Microsoft Paint as the list of features in the “removed and deprecated” list for the Windows 10 Fall Creators Update (known as Autumn Creators Update in certain regions) coming this fall. Microsoft first introduced the world to Microsoft Paint 32 years ago in 1985 as part of Windows 1.0.

There is a chance that Microsoft Paint will be in the Windows 10 Fall Creators Update, but Microsoft will no longer actively update the graphic editing software. And Microsoft has not specified when exactly the graphic editing software would be removed.

As a replacement for the original Microsoft Paint software, Microsoft released Paint 3D in October. Paint 3D allows users to share their work online.

Another application that is being removed in the Windows 10 Fall Creators Update is Outlook Express.

Microsoft Joins The Smart Thermostat Game Market

Microsoft has partnered with Johnson Controls to launch a smart thermostat product called GLAS. Johnson Controls is known for creating the first electric room thermostat.

The GLAS smart thermostat will run on the Windows 10 IoT core operating system. And the GLAS smart thermostat is going to have a translucent touchscreen that supports Cortana voice commands so you do not have to talk to your phone or a smart speaker to adjust the temperature. Plus the GLAS device will be able to detect the presence of users in the room and detect air quality indoors and outdoors.

Microsoft To Provide Azure Cloud Services At A Global Scale For Baidu’s Self-Driving Project

Microsoft and Baidu have announced a partnership in regards to the adoption of autonomous driving worldwide. Microsoft is already a member of Baidu's Apollo alliance and will provide a global scale with the Azure cloud outside of China going forward.

But now, you’ve gone and stuck this image in the Easter egg section of the latest Android O developer preview, replacing the original placeholder Easter egg that traditionally has been there to keep the real name of the OS a secret. This is clearly an intentional move, given that the earlier Android O previews would only show the “O” logo on a space background.

Thus, the cartoon Android octopus begs a serious question: does Google think octopus is a dessert?

Now, octopus is certainly a food, enjoyed by millions as a delicacy around the world. It can be served as part of sushi, fried, or prepared in any number of ways. But the overwhelming consensus of the culinary world would indicate that it’s not a dessert! The closest thing we can find to a dessert version of octopus is a Trolli octopus gummy, but Google’s Easter egg seems to lack the multi-colored hues that the candy treat is known for.

It’s possible the folks at Mountain View are simply confused. Or maybe Android is switching away from dessert nicknames entirely. Perhaps the entire thing is an elaborate troll designed to drive the denizens of the internet mad! Is the black-and-white color scheme meant to serve as a visual placeholder for an Oreo cookie? We need answers!

Update: Shortly after this post went live, my colleague Natt Garun made the shocking connection that Android O is also Android version 8.0. Octopi are known for having eight legs. What exactly this means for the mascot of Android O is as yet unclear.

The final version of Android O — whatever it ends up being called — is expected to release sometime later this summer.

By analyzing satellite images, the scientists found evidence of water trapped in "glass beads" in ancient ash and rocks that volcanoes spewed across the surface of the moon, said Ralph Milliken, lead author of the new research, published in Nature Geoscience, and an associate professor in Brown's Department of Earth, Environmental and Planetary Sciences.

"The fact that nearly all of them (the volcanic deposits) exhibit signatures of water suggests ... that the bulk interior of the moon is wet," he said in a news release.

This finding might be a boon for future missions to the moon because water could potentially be extracted from the volcanic deposits, Milliken told CNN.

Though the volcanic glass beads don't contain much water -- maybe a few hundred parts per million -- there's a great deal of the volcanic material to work with, Millliken told CNN. Some fields of this volcanic refuse cover thousands of square kilometers and may be several kilometers deep, he said.

"It's more water than previously recognized," he said.

Volcanic glass beads

Previous findings of water on the moon didn't appear to come from indigenous sources, Milliken said.

In 2009, NASA announced it had found water on the moon. One ton of the moon's surface might yield 32 ounces, NASA scientists said.

Scientists speculated those crystals might have been created by solar winds that interacted with hydrogen at high altitudes, Milliken said. There are also small amounts of frozen water at the moon's poles, he said.

Scientists believed the moon was dry when the Apollo missions started in the 1960s. That thinking changed in 2008 when volcanic glass beads brought back by the Apollo 15 and 17 missions of 1971 and 1972 were found to contain tiny crystalline formations that contained water, the Brown news release said.

But nobody knew if those Apollo samples represented the whole moon or just unusual spots on an otherwise dry surface, Milliken said.

Scientists at Brown took another look at images of the moon's surface retrieved from the Moon Mineralogy Mapper, an imaging spectrometer that flew aboard India's Chandrayaan-1 lunar orbiter in 2008.

These images showed materials never examined by the Apollo missioins. After developing a "thermal correction" that separated the readings of reflected light and heat, scientists were able to collect data showing evidence of the glass beads in nearly all the volcanic deposits spread across the moon, Brown said.

"The distribution of these water-rich deposits is the key thing," Milliken said in the news release. "They're spread across the surface, which tells us that the water found in the Apollo samples isn't a one-off."

The study was funded by NASA.

With OpenSpace, you can fly over Martian mountaintops and swoop through the deep canyons of Valles Marineris with the highest-resolution views from NASA's Mars Reconnaissance Orbiter (MRO), creating sort of a Google Earth for Mars. And that's just the beginning; the makers of OpenSpace said they aim to ultimately map the entire known universe with dynamic and interactive visualizations created from real scientific data.

Using data and images from the Context Camera (CTX) on MRO and the Mars rovers Spirit and Opportunity, researchers have already mapped 90 percent of the Red Planet's surface down to a resolution of about 20 feet (6 meters) per pixel. Incorporating high-resolution images from the spacecraft's HiRISE camera (High-Resolution Imaging Science Experiment), OpenSpace has allowed researchers to image parts of Mars down to a resolution of about 25 centimeters (10 inches) per pixel. That's 24 times sharper than before. [Latest Photos from NASA's Mars Reconnaissance Orbiter]

NASA and SpaceX have used HiRISE to look at potential landing sites for upcoming robotic missions like the Mars 2020 rover and Red Dragon sample-return mission, because the camera can resolve details in the terrain and determine whether it's safe for a rover to touch down and drive around there. When HiRISE isn't looking at landing sites, scientists use it to study other aspects of the Martian surface.

Since MRO arrived at the Red Planet 11 years ago, HiRISE has taken more than 4,500 stereo images of the Martian surface. The U.S. Geological Survey has so far gotten around to processing only about 380 of these images to incorporate them into a map of the Martian terrain.

Signals From Red Dwarf Star Ross 128

The radio signals, which were picked up on May 12 using the Arecibo radio telescope, appear to come from the red dwarf star called Ross 128. The star, which is about 2,800 times dimmer than the solar system's sun is not yet confirmed to have any planets.

Astrobiologist Abel Mendez, from the University of Puerto Rico at Arecibo, said that the bizarre, "almost periodic" signals were picked up during the observation of the star that lasted 10 minutes.

The SETI (Search for Extraterrestrial Intelligence) group is aware of the mysterious signals. SETI Institute astronomer Seth Shostak said that the Allen Telescope Array in California may be used to check the signals. Nonetheless, he said that these are likely terrestrial interference.

"The chances are high that they're terrestrial interference, in fact. That's really always been the case," Shostak said.

Are The Signals From Intelligent Alien Life?

The idea of alien life usually crops up whenever scientists detect bizarre or unexplainable signals from space. Some scientists, for instance, considered the possibility that the dimming of the Tabby's star could be explained by an alien megastructure orbiting around it.

Mendez thinks it is unlikely that the newly detected signals from Ross 128 is due to intelligent extraterrestrial life but noted that this possibility cannot yet be ruled out.

Possible Explanations

The astronomer said that the signals could be explained by something that humans have put in space, such as a satellite that passed overhead. Another possible explanation for the signal is a stellar flare, an outburst of energy from the surface of the star. Flares from the sun emit powerful radio signals that can disrupt satellites and communications on Earth.

"We do not know the origin of these signals but there are three main possible explanations: they could be (1) emissions from Ross 128 similar to Type II solar flares, (2) emissions from another object in the field of view of Ross 128, or just (3) burst from a high orbit satellite," Mendez wrote.

Astronomers said that each of these three possible explanations for the signals has problems so further observations will be conducted in the hopes that these could shed light on the nature of the radio emissions.

The business magnate participated in a question and answer session with Nevada Gov. Brian Sandoval, the incoming chair of the National Governors Association, whose initiative explores how state leaders can prepare for and benefit from innovative technologies.

Musk made his stance clear that governors must address artificial intelligence proactively, or it will be too late. Without proper regulations in place, he warned, industries will become completely autonomous, posing a threat not only to jobs but to the nation's safety. He said the government "doesn't have insight" into AI yet but, when they do, "I think people will be very afraid, as they should be."

Robots can complete tasks faster and more efficiently than humans, but even more dangerous is the fact that they could "start a war by doing fake news and spoofing email accounts and fake information, and just by manipulating information," Musk told the audience.

Responding to Musk's somber warnings, the governors were eager for advice on how to defend their states.

The entrepreneur said state legislators should start by forming a regulatory committee, whose first task would be to develop a full understanding of AI.

He stressed the importance of forming regulations to prevent companies from building their artificial intelligence to keep up with competitors who are doing the same.

"If your competitor is rushing to build AI and you don't, it will crush you, " Musk said.

Arizona Gov. Doug Ducey, who has worked to reduce and eliminate these regulations, expressed concern over upsetting the balance between regulation and entrepreneurship.

Though some companies will threaten to relocate to China, or to a country with more lenient regulatory policies, Musk says they won't follow through in doing so unless the state policies are "really overbearing."

During a lighter portion of the session, Musk also made some major predictions about the future of cars. He said he guesses that in 10 years, more than half of all new vehicle production in the U.S. will be electric and that nearly all cars produced will be autonomous. But with some older cars on the road, it will take longer for the entire U.S. fleet to become autonomous.

Earlier this week, McGregor and Mayweather took part in an international press tour to promote their multi-million-pound boxing match, which takes place at the T-Mobile Arena in Las Vegas, Nevada on August 26.

As expected, the two biggest names in combat sports threw several verbal jabs at one another, much to the delight of their respective set of fans.

The trash talk reached a whole nother level on Wednesday evening at Budweiser Stage in Toronto, the venue for the tour’s second press conference.

A fired up McGregor, who was fuming at Showtime for cutting his mic during his speech at the Los Angeles event, roasted Mayweather on a whole host of topics.

Never one to hold back, McGregor slammed his upcoming opponent for his current financial woes and his alleged inability to read.

Mayweather tried his best to get one up on ‘The Notorious’, repeatedly calling him a ‘b**ch’ and an ‘eejit’.

The former five-weight world champion’s taunts weren’t well received by the crowd and he resorted to shouting, ‘I’m the best, I’m the best.’

McGregor mocks Mayweather's strip club in trash talk

UFC commentator Joe Rogan has been keeping a close eye on the verbal battles between McGregor and Mayweather and believes the latter has been shaken to the core.

“Conor’s hilarious, man,” he said during a recent episode of his Joe Rogan Experience podcast. “He’s f***ing hilarious.

“He’s laughing and having a great time and Floyd seemed a little rattled by how confident this guy is when they were going face to face and standing off with each other."

Rogan might have given McGregor the nod for the mental warfare side of the fight but is sticking to his belief that the reigning UFC lightweight champion faces an almighty task to become the first man in history to beat 'Money' Mayweather.

"The thing about Floyd is I think you have an idea of what you can do to him until you get into the ring with him, and then you realise how good he is,” he added.

“His defense is just on another level, he’s just in a completely different zone all by himself.
