Hacking into my account won't give the perpetrator access to a password-protected document; Recall would.It also gains access to passwords in Windows' password manager, payment methods in your browser, cookies, access to all your drives, etc.
Recall or not, you're cooked if a bad actor gains that much access to your machine.
The more I think about it, the more this feels like the folks at Microsoft being tasked by management to come up with AI-infused software tools just so they have something to show to investors, never mind how inane or useless it may be. The end result is something like Recall, which while technically impressive, strikes me as a solution looking for a problem.
I am still struggling to see the point of this feature. Let's say I can't find a document or delete it by mistake. I can use recall to .... hopefully search for a screenshot of me working on it some time in the past, and then I still have to recreate the file from scratch?
Nobody in their right mind would be hitting "print screen" on their keyboard every 5 seconds while they work, so why would I want the OS doing it for me?
