I was surprised to learn that Worldcoin is still running. It's a huge scam; it's a pyramid scheme designed to harvest biometric data, and enrich its creators in the process. I thought it was silently buried after the initial backlash.
I read the "pyramid scheme" (given the rest of the comment) as an accusation that it exists primarily to monetize the biometrics that individuals provide of themselves and any effects like "people can authenticate themselves online with our service" are secondary.
This doesn't rule out Worldcoin being wrong, though. (See the whole "data is the new oil" phase).
