It feels like Microsoft is really going all in on this AI trend. Probably because they are well aware that they missed/were late to every major trend since the 90s (e.g. the Internet, music players, smart phones, gaming consoles,...) and they don't have that much to lose any more with Windows' inferiority becoming more and more apparent. So they are probably going for the high risk, high reward strategy where they will either lose the desktop OS market completely (in the likely case AI turns out to be just a regular hype cycle) or win big by being early (in the unlikely case that AI turns out to be much better than it looks like right now AND having expertise with this will help with better versions of this once they show up).
