I don't think microsoft has the culture to be competitive on the cutting edge of AI.
If they try to integrate OpenAI, they will suffocate it.
So did Google some with DeepMind.
All the big innovations were at DeepMind, and then they got bought, stifled and absorbed.
Big companies have a hard time innovating, so buy it.
And then, 80% of the time, they suffocate what they bought.
