Everyone’s heart is different. Like the iris or fingerprint, our unique cardiac signature can be used as a way to tell us apart. It can already be done from a distance using lasers [1].

- pempem 1y agoAh yes, tracking everyone. The one system that only leads to good outcomes.
- lemonberry 1y agoWell, we know that tracking "everyone" would only lead to tracking a subset of everyone. A subset with a lot less money and power than those in charge of the tracking. Much like the guard or observer in the panopticon.

- anonporridge 1y agoThat only catches the stupid criminals, which to be fair is most of them.
- palata 1y agoNot sure how many criminals that catches, but phones most certainly track everybody.
- nashashmi 1y agoThe CEO killer in NYC could have been tracked this way.
