This whole affair leading to Sam and Greg joining Microsoft means this new venture to develop a competing processor to those from Nvdia will happen faster than it would have at Open AI. While the billions that Microsoft poured into OpenAI (largely to accomplish this) are basically a writeoff now, they will spend even more billions to develop it in house instead. Only a small speed bump that will probably bring it about even faster in the long run and give Microsoft total control. They won’t have to share it with competitors.
