Tbf I’m okay with a lot of this stuff as long as it stays local on your own PC and you have control over it. However I don’t trust MS to implement it in a way that doesn’t prioritise their profits over my privacy.
Furthermore, I don't trust Microsoft to not do a gigantic oopsie and introduce a bug that emails screenshots of porn websites I visited to my Mum or some shit. Their QC is abhorrent.
Soon: "We've notice there was a backdoor for 20 years, in that open source library, that was actively abused, that allowed for full access to the AI remind me recordings." upsi daisy.
The bug was well documented and we own the git platform it was written on, but hey, we ain't got time for that. Too busy implementing new menus that look worse and do less than the old ones so we have to keep the old ones around anyway.
Available information indicates that it's all processed and stored on-device (and even encrypted). I'll wait for confirmation from security researchers, but the available information I've come across says that it's all done locally.
