> who the eventual dominant player(s) will be

This couldn't have been easy. The team at OpenAI has worked a miracle.

  For example, Meta and Microsoft’s AI ASIC programs not getting off the ground despite being at it for much longer shows that cost is only one part of the equation.

I bet cost is of no issue with the capx where it is at. It is almost certainly organizational. Meta throws money at every problem and it never seems to workout for them.
