>But then I read about things like WorldCoin and that people who go to startup parties jump at the chance to give away scans of their retinas and I'm befuddled.

I'm befuddled that anyone thinks Sam Altman is the least bit trustworthy after WorldCoin.

There is a difference between genomic data and biometric data: biometric data has a known potential exploit vectors. So, with a picture of your retina, a sophisticated adversary could potentially reproduce your retina to allow access to some secure facility.

Genomic data doesn't have the same risk factors--at least at the moment. I think that the point many are trying to make here is that there may be risk vectors available at some point in the future that aren't known now. A couple of theoretical examples:

* You had to give a blood sample rather than other biometric data like a retina scan.

* Spoofing DNA evidence. That would be very/prohibitively expensive/difficult at the moment, but I suppose could become as easy as 3d printing at some point in the future.
