In theory the unique id produced by the scan could be salted by you, uniquely for each website or application, and then provided to the site. This would keep aggregators from being able to track all your activity, or at least it would if they didn’t already have fingerprinting techniques that do it without the need of another unique identifier.
Problem is they aren’t required to prove it to you - some witness - unless it’s your child that’s involved, and they can take their sweet time providing proof to the person being detained as well, waiting until they’ve already thrown you to the ground and cuffed you.
A face can be seen, recognized and recorded from a distance. Video doesn’t usually do any good with badges and other identification but cops and criminals both - or one and the same - risk being identified if they don’t have masks.
That used to be true but no longer. For anything but gaming Apple’s M series chips are amazing.
I’m a 30+ year Windows and Linux user and developer that preferred machines I could build myself. A few years ago switched jobs and was given an M1 Pro for work… it’s incredible how good, fast and low power the M series are. I’ve used my laptop 8 hours straight without plugging it in. That’s simply not doable with any other machine.
I still dislike their walled garden, and for high end gaming Apple’s a no-go, but for most things it’s hard to argue with how good they are. The machines may come at a premium, but they are high quality, work great and for battery use they don’t have a rival.
