Why implants? They are such a hassle to upgrade. I thought we'd skip them entirely and go from wallets to phones to fingerprints. And then to a central AI that can recognize you from a video feed.
I don't know how many times people need to repeat this: Fingerprints are usernames, not passwords. I am really not a fan of biometrics as identification at all.
Fingerprints are neither usernames nor passwords; fingerprints can be destroyed independently of the user, usernames should not be destroyable as long as the user exists. Fingerprints are more something that is suitable as an optional proxy for a username.
Its about the same reason that I don't want Apple to do a TV. The difference in lifetime between the computing component and display are immense. Implants would seem to be as short a lifetime. Credsticks always made more sense.
