What do you think, ChatGPT? If it can create almost perfect summaries with a prompt; why wouldn’t it work in reverse? AI built into Windows could flag potentially subversives thoughts typed into Notepad or Word, as well as flag “problematic” clicks and compare it to previously profiled behavior. AI built into your GPU could build an behavioral profile based on your interactions with your hentai Sonic the Hedgehog game.
Ads? You mean those stickers on a bus?
Seriously though, use DNS, VPN and other means to block ads and telemetry, so thoughts like that don’t even occur to you.
