Ever since the movie "Demolition Man", it should be obvious why biometrics are a bad idea. (Yeah I know they also can try to scan for signs of life like blood flow - still, I don't like it).

Even without the Demolition Man scenario, an even worse issue is that you can't change your biometrics in case somebody steals them. Fake fingerprints are already easy to do, other things surely can be cloned, too.

Worldcoin issues tokens to people for scanning their retinas. Their magical orb device sends a biometric hash to their network.

Here's my take on it: You can possibly replace their biometric device with a random hash generator.

* If it works, it means the currency is not fairly distributed, but anyone sending valid hashes to their network is issued tokens, irrespective of whether the eyeballs described by those hashes exist. This is called a Sybil attack.

* If it doesn't work, it means there is some secret or centralized check that the network performs, which means the currency is not open.

This is why we still use proof-of-work in spite of its energy expense: it is simple to understand, it can not be faked, and it can be openly verified.

So, do not support this biometric-gathering enterprise.

Kids or coworkers are not going to make fake fingerprints to mess with me. What they can do is to see password or pin code while I am typing those over my shoulder. Someone on the street also won't be able to see my pin code for unlocking phone if I use fingerprint.

Those are scenarios that biometrics are handling really well.

Biometrics against sophisticated attackers is not good idea. I don't encounter in my life "sophisticated attackers" that would spend time making copy of my fingerprint.

If you are person that has risk of running into sophisticated attackers then don't use biometrics and biometrics are bad idea.
