GenAI is hotter than anything else right now. As Satya publicly stated, "we made them dance" -- which shows how high-priority it is to maximize "AI innovation" at MS.
If you disagree, think about how badly "Tay" blew up in MS's face and yet they still went ahead and bundled OpenAI LLM tech into all of Office365, just so they could have bragging rights about beating Google to it.
At this point, it's a race (to where? who knows) and no Big Tech Corp wants to be seen as "not at the forefront".
That's my $0.02, anyway :)
