I honestly can't wait to use used gpus as lego bricks similar to what kids in Weimar republic did with cash
The most likely outcome is kids in third world countries extracting the valuable metals from piles of discarded GPUs.
Never gonna happen. Cash has no intrinsic value exccept maybe for use in fire / toiler paper. GPUs while currently inflated in price will always find enough value. Their price might go down 50-75% but never 99%
My self-training robot army is poised to conquer all. It's merely waiting for parts.
Soon you will bring a wheelbarrow of GPUs to buy a loaf of bread.
