The only thing I can imagine is that both Apple and Microsoft will bog down the desktop equally in AI garbage, to the point where both are approximately equally unusable.

Briefly, with an example: instead of going through menus looking for the option you need, you can just tell the AI (with a voice command) what you want to do. At that point it does not matter who has the nicest menus.

Advanced users are already seeing this. You don't need HandBrake anymore. You can just use ffmpeg directly and ChatGPT will tell you the command line arguments.
