Even if consumer can eat all the gpus, it cannot have the margins (as you say), and thus won’t sustain the current valuations all these companies have and which fuel the (necessary) investments.

NVIDIA is sitting on 74% gross margin. If we reach a place where "all" these companies have to do to unlock nearly unbounded demand is take lower margins, they will find capital.

If anything I'm more worried about the consumers than the companies.
