you mean how google scans everyone's fingerprints and apple scans everyone's faces?
Worldcoin on the other hand went to the third world and went through Africa offering people almost a month's wages to give up their biometrics. That, to me, should merit a deeper dive into what they are doing and why.
If fingerprints and faces are the same as retinas, where do you draw the line - or is there just no privacy line for you anywhere, as long as a billionaire somewhere is making lots of money?
