Earlier quoted context omitted.
I mean the root comment pretty much already explained it. It is literally impossible for Worldcoin to actually perform its stated purpose, therefore it's a scam.
It is literally impossible for a simple deadbolt to keep intruders from entering your house. Are locks scams? Separately, I strongly suspect that your idea of worldcoin's "stated purpose" is not something they have ever stated.
I encourage you to read their whitepaper, where they state that world id is indeed a proof of personhood. The allegation in this thread is that it fails at proving that someone is a unique person, and it cannot possibly due so because of the oracle problem. Therefore it is a scam.
