The billionaire tech entrepreneur called AI more dangerous than nuclear warheads and said there needs to be a regulatory body overseeing the development of super intelligence, speaking at the South by Southwest tech conference in Austin, Texas on Sunday.

It is not the first time Musk has made frightening predictions about the potential of artificial intelligence — he has, for example, called AI vastly more dangerous than North Korea — and he has previously called for regulatory oversight.

Some have called his tough talk fear-mongering. Facebook founder Mark Zuckerberg said Musk’s doomsday AI scenarios are unnecessary and “pretty irresponsible.” And Harvard professor Steven Pinker also recently criticized Musk’s tactics.

Buzz Aldrin, the second man on the Moon, once said, “Mars is there, waiting to be reached.”

If Elon Musk has his way, he’ll be the one to reach it, even if it’s likely to be a dangerous journey that could result in the loss of human life.

Speaking at the South by South West festival in Austin, Texas, SpaceX and Tesla CEO Musk said he envisions test flights of his Mars spacecraft next year, though he cautioned early trips could end in death.

But hyperloops are no longer quite so hypothetical. A handful of firms are now competing to develop the necessary technology. And in addition to designing the magnetically levitated pods and testing them on small-scale tracks, the firms are taking preliminary steps to set up hyperloop routes in the U.S. and abroad.

“It’s happening far faster than I would have ever expected, and it’s happening all over the world,” said Dr. David Goldsmith, a transportation researcher at Virginia Tech.

One of the biggest players is Musk himself. His whimsically named Boring Company is planning to dig a hyperloop tunnel that would make it possible to travel from Washington, D.C. to New York City in half an hour (the fastest Amtrak trains make the trip in just under three hours). Meanwhile, a pair of California-based startups, Virgin Hyperloop One and Hyperloop Transportation Technologies, are developing routes in North America, Asia, and Europe.

In a recent interview, Microsoft co-founder and billionaire philanthropist Bill Gates told The Wall Street Journal he disagrees with Elon Musk’s assertions that artificial intelligence is a significant threat to humanity.

Artificial intelligence (AI) is one of today’s hottest topics. In fact, it’s so hot that many of the tech industry’s heavyweights — Apple, Google, Amazon, Microsoft, etc. — have been investing huge sums of money to improve their machine-learning technologies.

Israel-based BrainQ is a new neurotech startup hoping to take on brain-computer interface (BCI) companies like Braintree founder Bryan Johnson’s Kernel and Silicon Valley billionaire Elon Musk’s Neuralink.

It’s not clear yet what Musk’s startup intends to do with the computer chips it plans to put in our heads, but Johnson’s startup says it is focused on developing “technologies to understand and treat neurological diseases in new and exciting ways.”

Whatever sector each company goes for, both plan to insert chips in our brains to connect us to computers — the consequences of which could have dramatic effects on human memory, intelligence, communication and many other areas that could rocket humanity forward, should they work out.

Tesla Inc. Chief Executive Elon Musk took to Twitter this week to decry the slow and costly pace of U.S. infrastructure projects, and thus a challenge — or boast — was born: The Boring Co. could build a tunnel across the San Francisco Bay far cheaper and far faster than current available estimates.

Musk was pointing to a San Francisco Chronicle editorial favoring a new Transbay Tube for public transportation over another cross-bay bridge to alleviate chronic traffic woes and public-transportation overcrowding in the Bay Area. The editorial cited a starting price of $12 billion for the new tunnel.

Probably about a tenth of the cost and a fifth of the time— Elon Musk (@elonmusk) February 28, 2018

When SpaceX launched the world’s biggest rocket ship on Feb. 6, that kind of seemed like a big deal — but not everyone is impressed.

Previewing the SpaceX Falcon Heavy launch, The Wall Street Journal seemed perplexed. Yes, the Falcon Heavy is big, admitted the Journal. But as a “heavy-lift booster,” it said, it is a product designed to serve a market that’s suffering “significantly eroded commercial demand” and “uncertain commercial prospects.”

The problem, as the Journal (correctly) pointed out, is that thanks to advances in rocketry, electronics, and materials technology, “both national security and corporate satellites continue to get smaller and lighter” (and cheaper).

Elon Musk has revealed his personal cryptocurrency holdings.

The billionaire CEO of SpaceX and Tesla told Twitter followers that he in fact has never purchased cryptocurrency, and only holds a small amount of Bitcoin gifted by a friend.

Not sure. I let @jack know, but it’s still going. I literally own zero cryptocurrency, apart from .25 BTC that a friend sent me many years ago.
