This completely breaks down under the current reality of AI investment, as players large and small are no longer price-takers. The marginal costs of investment are not constant because we have finite supplies of GPUs, TPUs, memory, hard drives, and power. The Hamiltonian in equations 5 and 6 needs to account for this.
are you saying that previous technologies had effectively infinite supply?
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.
Citation needed. Industries that faced multi year supply constraints in recent memory include: nuclear power, battery manufacturing, flagship commercial aircraft models, late-stage pharmaceutical safety certification, certain luxury cars, and more.
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.
