Thompson is speaking broadly about markets, not trying to put anyone down. The point he's getting at is that Apple and MS are just playing (or trying to play) to their strengths. Did you see anything in the new Siri AI demos that looked all that much like someone getting work done? I didn't. And that's fine, for Apple and the iPhone. Microsoft for better or for worse is what a large part of the American business world is using to get work done, and so Microsoft is trying to position their AI strategy towards that.
For what its worth I wish Apple would care more about those of us that want to use AI to actually do work and not these weird contrived examples asking if focaccia can be made gluten free. And I personally couldn't care less what Microsoft does as I'm lucky enough to never have to use their products outside of Github.
