If you wanted to create a user authentication system that could reliably differentiate between humans and AI, how would you do it? Not trying to defend worldcoin. It's just that this problem of differentiating people and AI online matters a lot to me and I haven't thought of a reliable way yet, even theoretically.

...differentiate between humans and AI, how would you do it? Make everybody play Where's Waldo? with a grid of 9 blurry pics. Except sometimes Waldo is a bus, bridge, or traffic light.

I don't think that there is a way to do this without an unacceptable level of sacrifice in terms of privacy/security. I hope my opinion is very wrong, but so far I haven't seen any sign that it is.

  For the record, I meant the same thing: (while maintaining privacy and security, eg while supporting anonymity). Blockchain attestations seem interesting but I'm not yet convinced by them. I'm glad there are people working on this problem though.

You can come close with requiring a phone number. If you need to know someone is a human with one account, you have to make them provide an ID. Usually you don't really need to do that.

  A computer can't have a phone number?
  - mminer237 3y ago
    Not really, no. Obviously a human can log in with his phone number for his bot, but he could do that with Worldcoin too.

      Have you never dealt with an automated text message? That's just a computer using a phone number. Robocalls can also come from AI chatbots that don't require a human.

        Sure, I realize that. But VoIP numbers are pretty easily filtered out and that imposes a cost which cuts down on most abuses of bots. Still, that's why I said, "You can come close".
