Unfortunately, you cannot buy gaming gpus, not because AI data centers are buying them, but because Nvidia would rather produce server GPUs than gaming GPUs. Same for memory. Once the AI bubble bursts, there still won't be gaming GPUs to buy unless Nvidia and everyone else switch production, and you cannot put a datacenter GPU in a regular computer.

When the COVID recession started, dairy farmers were seen dumping surplus milk rather than sell it at a lower price. I foresee a version of this where companies start destroying silicon to keep the supply low rather than let the prices drop to sane levels.

Older PCs and consoles are only cheap now because people buy newer stuff.

When the newer stuff becomes prohibitively expensive, old hardware and consoles will SKYROCKET as demand goes up, because nobody is MAKING more.

Hoard tech now. We're not that far away from 2012 laptops going for $500.

4th ending doesn't matter because after the AI bubble pops companies will do mass layoffs to reduce costs and nobody will have the income needed to buy components at normal price. By the time things start to stabilize there'll be some new reason consumers are priced out of the hardware market.
