Is your answer to "where can I buy a TPU" that you can't buy a GPU either? That's a new one.

First of all I don't understand how that's an answer. Second of all it's laughably wrong - I can name 5 firms (outside of FAANG) off the top of my head with >1k Blackwell devices and they're making very good money (have you ever heard of quantfi....). Third of all, how is TPU going to conquer absolutely anything when (as you admit) you couldn't run one even if you could buy one?
