It's not that supply was actually infinite, but you didn't realistically have situations where you said "I want to buy GPUs for a data center" only to be told "there's a 3 year waiting list."

You might have two months after NVidia 3090s came out where they were short, but it is nothing like today.

No. I'm stating where the paper's assumptions are clearly violated.

AI companies are intentionally trying to monopolize the supply of inputs needed for R&D. This violates homogeneity of degree 1.
