NVDIA has plenty of other business and will not drop to 0. Even if they drop 75%, than is still only a 2-3% (the math on percentages is weird and I don't feel like doing it - and I shouldn't because a 75% drop is just a random number and so I have no significant figures to work with) drop in my 401k. Of course other companies will be hit as well, but still my 401k will not drop and more than any other stock market crash, and there is every reason to think it will recover. It might stop my plans to retire in the next 10 years (but they were of questionable realism anyway), but any longer than that and odds are it will recover.
That's literally one company being used to make a point. At least 25% of the S&P is composed of highly AI-leveraged companies.
And you're acting like massive market changes don't propagate and won't cause ripple affects across the economy that impact other markets and change the view of financial risk.
Most companies have non ai business. They will fall but it won't be to zero. Bubbles have poped before, and they have been leveraged too. There will be some bad years - but in 15 years things will have recovered and we will be on the next bubble
