• Elon Musk says "money becomes irrelevant" if he's right about what the future holds.
• The Tesla and SpaceX CEO said AI and robots will be better than humans at everything.
• The world's richest man said his fortune could be virtually gone within a few generations.

Elon Musk says money could be meaningless one day, and the vast majority of his wealth will likely be gone within a few generations.

The world's richest person predicted that advances in robotics and space travel will create a multiplanetary economy, at which point "money becomes irrelevant" and "conventional currency will not matter."

Value will be measured in mass and power or energy, he continued. "So that's my guess," he said, adding that it seemed a "pretty obvious" outcome to him.

The Tesla and SpaceX CEO shared his vision of a post-money future and his outlook on his personal fortune with his biographer, Walter Isaacson, on "The Builders" podcast. The interview was taped in early August and released on Tuesday.

Musk recommended earlier this year that people stop saving for retirement in 10 or 20 years, as he expects AI and other technologies to supercharge productivity and usher in an age of abundance where people can have "whatever stuff they want."

He made a similar argument to Isaacson, saying "there won't be anything that humans can do that the AI and the robots can't do better." People will likely turn to hobbies like growing their own fruits and vegetables, or making art, to find purpose in life, he said.

Musk's plans for his own money

Musk, who briefly became a trillionaire after SpaceX went public in June, topped the Bloomberg Billionaire Index at Monday's close with an estimated $920 billion net worth.

He defended his personal wealth on the podcast, saying that it mostly reflects his ownership of SpaceX and Tesla, and he needs large stakes in both companies to retain voting power and remain in charge.

His fortune is "going to be taxed quite heavily," Musk said, adding that there isn't "some magical way to avoid taxes" because "if there were, I would know about it."

Musk said his wealth will "get whittled down and a few generations from now — if money still matters, which I don't think it will — my descendants would have a tiny fraction of what I have."

He also outlined what he hopes his foundation will spend his fortune on after he's gone: "Continue the goals. Make life multi-planetary, extend consciousness to the stars, improve sustainable energy on Earth."

Notably, Musk pledged on Monday to gift a share of SpaceX to every child in the US next year, a contribution worth over $10 billion today.

His announcement has won praise from President Donald Trump, who hailed Musk's "incredible generosity" and labeled him a "legendary friend" in an X post.

Musk teased a charitable pledge in late July after Nobel economist Daron Acemoglu publicly challenged him over his prediction of a post-money future.

"If money won't matter in 2036, why don't you pledge to donate your current wealth of approximately $1 trillion to charity no later than 2036," Acemoglu wrote on X.

"I am actually going to do something along these lines!" Musk responded.

The Tesla Roadster demo was brilliant theatre but who in Ireland decides if a car like that can use our roads if it ever goes on sale?

One of my favorite cartoons growing up was "The Jetsons." The Jetsons were a futuristic family living among the clouds with a fully automated life, from a robot maid named Rosie to technology that could make your dinner or do your laundry in just a few seconds at the push of a button. Everyone’s favorite aspect of this futuristic cartoon lifestyle boiled down to one element, which has become somewhat of a benchmark for technological progress: flying cars. And with Tesla’s recent exhibition, we are one step closer to that Jetsons-esque reality.

If you haven’t seen the video, Tesla did a demonstration of their forthcoming Roadster vehicle, slated for 2028 production. The car swooped up a half-loop ramp reminiscent of Matchbox car stunts. At the top of the ramp, the car, which was upside down at the top, flipped over in midair. Then, thrusters seemed to suspend the car in midair, before helping guide it gently back down to land on the ground.

For just a few moments, that car flew, and it was truly awe-inspiring.

FLYING SPORTS CAR HIDES ITS WINGS AS PRODUCTION GETS CLOSER

The reactions to this engineering feat and demonstration spectacle are somewhat of a Rorschach test. Those who love building, progress, technology or who are just generally optimistic have seen this demonstration as a formidable, impressive achievement. Those who like to see things torn down or are generally naysayers or obstacle formers react with "it’s not that big of a deal" or give other criticisms.

Fortunately, America still has enough people committed to the entrepreneurial spirit to attract the likes of Elon Musk and provide a good home base for his talented team members and others who want to see Musk, America and human beings in general succeed.

It isn’t hyperbole to say that Elon Musk is one of, if not the greatest, entrepreneurs of modern times. Regardless of any personal feelings or thoughts about Musk, if you can separate the art from the artist, or in his case, the entrepreneur from his business accomplishments, objectively, Musk has done the unthinkable time and time again. And we, as a country, are better off for him doing it from America as his home base.

As my husband and I talked about Musk’s varying accomplishments, from his early work in online payments to his achievements in electric vehicle manufacturing and AI, to his SpaceX being able to catch rocket boosters returning to the Earth from outer space upon landing, and now this latest hovering automobile. We discussed that Musk reportedly held discussions with Taiwan Semiconductor Manufacturing Company regarding a potential collaboration for his "Terafab" semiconductor facility in Texas. I mentioned that chip buildout had faced major challenges elsewhere, and my husband pointed out that it is different under Musk, saying, "In fact, we need 16,000 more Elon Musks."

INNOVATION IS KEY TO AMERICA STAYING A SUPERPOWER. BUT IT IS MISSING AN ESSENTIAL PIECE

And he’s right. America needs more Elon Musks.

No, Elon Musk does not succeed on his own. There are many team members alongside him in undertaking outrageous projects and often making them succeed. But there’s something about Musk’s vision, leadership, hiring and willingness to inspire confidence in others, both on his team and in the general public, that makes his teams continue to be successful. And we need more of that.

We need to not only attract and inspire those who may even be just a little bit like Musk, to dream bigger and bolder, to take calculated risks and try and try again when things don’t work the first time. And we need to make sure that we incentivize that behavior, instead of trying to penalize it or throw up roadblocks.

THE NEXT AMERICAN BOOM COULD BE HERE — UNLESS WASHINGTON REGULATES IT TO DEATH

In our own government, which is supposed to help vs. hinder entrepreneurs, we have politicians like Senator Elizabeth Warren, who is noted for going after Elon Musk because of his success, instead of trying to figure out a way to foster more Musk-like successes. After a vastly-ridiculed post made earlier this week from Warren lamenting, of all things, a possible merger between companies that make various spices and condiments, Mike Solana, CMO of Founders Fund and EIC of Pirate Wires, posted on X (also owned by Musk), highlighting the stark differences between the politician Warren and the creator Musk.

His post said, "liz warren: we’re gonna stop the mayonnaise company from buying a hot sauce company." He then said, "elon musk:," and included the video from Musk of the Roadster’s hovering feat, perfectly illustrating how some in our country are erecting barriers and others are breaking barriers.

America was founded on an idea of individual rights and incentives that rewarded successful pursuits, with such rewards growing at scale. We are very fortunate that we have Elon Musk and others who are pushing boundaries, bringing us into new frontiers, allowing Americans who work for him, who invest with him and who use his products or services to benefit alongside of him.

We do need 16,000 more Elon Musks. And the way to foster more Elon Musks is to appreciate, incentivize and reward entrepreneurship.
