I consider it to be very careless to entrust your emails, your chats, your calendar, your notes, your calls, your pictures, your contacts, your location history, your waking hours, your files, your TODO list, i.e. stuff including your health data to the for-profit AI companies. The temptation to earn money with your data is just too great, plus the risk of the data being stolen and sold illegally.
Local AI should be the default. For everone who can't do local AI, we need confidential compute. Yes, it has been hacked before. But it's making it a lot harder.
