That makes no sense. If the bubble bursts, there will be a huge oversupply and the prices will fall. Unless all Micron, Samsung, Nvidia, AMD, etc all go bankrupt overnight, the prices won't go up when demand vanishes.
That assumes the bubble will burst, which it won't if they succesfully corner the high-end compute market.
It doesn't matter if the AI is any good, you will still pay for it because it's the only way to access more compute power than consumer hardware offers.
There is a massive over-buying of compute, much beyond what is actually needed for the current level of AI development and products, paid for by investor money. When the bubble pops the investor money will dry up, and the extra demand will vanish. OpenAI buys memory chips to stop competitors from getting them, and Amazon owns datacenters they can't power.
