Tesla CEO Elon Musk has a message for people stashing cash in their 401(k)s: stop worrying about it. According to the billionaire, retirement savings might become completely obsolete within the next few years.

Speaking on a recent episode of the "Moonshots with Peter Diamandis" podcast, Musk painted a picture of a future where AI, energy breakthroughs, and robotics create such abundance that everyone enjoys what he calls "universal high income." Think less Universal Basic Income, more everyone is just wealthy.

Musk, whose personal net worth exceeds $600 billion, predicts this technological leap will deliver "better medical care than anyone has today, available for everyone within five years" and eliminate scarcity of goods and services entirely.

"If any of the things that we've said are true, saving for retirement will be irrelevant," Musk said.

"One side recommendation I have is: Don't worry about squirreling money away for retirement in 10 or 20 years. It won't matter," he added.

The Bumpy Road Ahead

Of course, Musk isn't selling pure optimism. He warned that getting to this utopia could be "bumpy," with social unrest and people potentially losing their sense of purpose. He even questioned whether a world where everyone gets everything they want is actually desirable, asking: "Now, if you actually get all the stuff you want, is that actually the future you want?"

It's worth noting that while Musk's companies are pushing the boundaries of technology, his prediction feels pretty disconnected from what most Americans are dealing with right now. Inflation, high interest rates, and wages that aren't keeping pace make the idea of abundant resources feel more like science fiction than near-term reality.

If Musk's vision somehow materializes, it would completely upend how society thinks about work, income, and retirement. But getting there without major disruption seems like the bigger challenge, one that Musk himself admits could involve serious growing pains.
