A nice thought.
Unfortunately the only ones who switch will be people 1. Know that it is even possible to switch/that they have an option to switch, and 2. Have the technical knowledge to back up their data, then download and install Linux, that 3. Don't have to run Windows for other reasons and/or haven't already switched.
Unfortunately with all three qualifiers you aren't left with a giant number. Certainly no mass exodus.
So, the AI chief dude is saying he doesn't understand why people don't want AI.... do they even read their own docs?
Here's what I see happening, probably very soon when this AI thing is released: Some malware developer writes an 'AI installer' that activates this thing, sets itself up as an AI on your PC, passes through whatever query you have to free ChatGPT, and then uses AI access to steal all your stuff or track you. Because if the AI model has access to your data, so does any support code related to that model.
