Nobody is able to build a chip that is competitive with NVidia's latest GPUs, not even AMD who would be next in line. Look at Google's TPU for a glimpse at a likely outcome of such an endeavor.

What it tells me is that Altman seems to believe that OpenAI can only make the next step if they can throw even more compute at the problem but that that isn't feasible at today's prices.
