Which is not a bad thing
Something that can work on any browser can be like this: Scan the QR code in your iPhone or Android device that supports attestation. Will ask you if you approve login, then will attest for you. If you turn out to be a bad actor, the website can ban this device - so no flooding with a single device.
These things are always cat and mouse games.
in upi system, you are presented with a QR code or you input your UPI ID, you click pay and it gets through.
if you are worried about "fraud protection", why rely on an intermediary like ebay or credit card company and instead should take up with your bank or the seller or courts.
The Internet will become a dark forest, and since that is where all of our communication and transactions happen of any significance, that’s pretty much game over for the significance of human activity.
Think I am overstating the fact? It already happened with wall street trading. First, institutions prefer bots to human. Then, you will come to prefer bots to humans. Then every human will be surrounded with 999 bots and unable to change anything or appeal to any significant number of humans to change anything.
It also does not help that the shown busses, water hydrants, pavements look totally unfamiliar to me. (Why aren't captures taken from all over the world Indian busses would be fun - London ones would be too boring)
(Amusingly, pain was proven to be preferable to boredom... and CAPTCHAS are boring as hell.)
