If you can identify a person, in any way, they are no longer private.

This is not necessarily applicable. There's cryptography from 20 years ago (e.g. the work of Stefan Brands) that can show that someone has a World ID without revealing which ID it is. If no "username" is ever revealed then it can't be linked to anything.

If the idea is to make "World ID" universal, in that everyone is going to have one, what does attesting that someone has one means? Nothing. Virtually nothing. Everyone either has one or can get one, to attest that they do means nothing of value.

I think the idea is that if you make a botnet of a billion bots you will not have close to a billion "world id"s (is that really what they are called? lol).

Maybe you can find a few thousand on the black market, but that's going to add up fast.

I know nothing really of this worldcoin latest hype. I think that attesting that you have one, without revealing who you are, could maybe be used to attest that you are not a bot? Maybe I misunderstand. Sounds interesting if true tho.
