I know it's a joke, but the hole is the god-AI couldn't have been that smart, since cryptocurrency-mining quickly switched to ASICs, which muting the demand increase for GPUs.
Did the GPU manufactures ever embrace cryptocurrency? IIRC, they actually tried to discourage it (e.g. by butting throttling into mass market models to discourage their use for computation).
Also, the graphs here show a long-term downward trend, with only a short-term sales blip 5 years ago due to cryptocurrency: https://www.tomshardware.com/news/sales-of-desktop-graphics-....
The talk/conversation appeared to me not as OpenAI future plan but more on the CEO lamenting on how severely limited the company by the GPU or the lack thereof. It just a cheeky ploy by a CEO of an AI company that currently at 30B USD valuation to get more money in order to buy several [fill in the blank] of these most advanced GPU systems [2].
