"Microsoft was born to do a certain set of things. We're about empowering people in organizations all over the world to achieve more. In today's world, we want to use AI to achieve that."

But even if Microsoft only pursues AI opportunities that it considers to be core to its mission, it has a remarkably broad tapestry to work with. And the examples that were part of the keynote made that clear.
