If you really want to Always Be Surveilling, wouldn't a better solution be a tiny cam/mic accessory that pairs with your phone/watch? You could use the same magnetic battery idea, but in a much smaller form factor. This thing (the Humane AI Pin) is aiming to be a phone replacement, which seems like a really steep challenge given its limitations--how could it replace any of the things I use my phone for on the subway to work?
