"However, it is worth noting that the most commonly utilized tools for enabling individuals to carry their identities with them are currently found in the Web3 ecosystem."

"Sign in with Google" would like to have a word with you. Scan your passport to link your account to your identity and Google can provide the ZKP-equivalent verification to a third-party that you're a person without sharing your passport. Are there some downsides compared to solutions like Worldcoin? Yes, but there are also advantages. Based on your own metric of usage, Google is used by about 1000x more people and has solid structural moats to maintain that.

"Based on your own metric of usage, Google is used by about 1000x more people and has solid structural moats to maintain that." -> Sign in with google proves that I have a google account, nothing more.

"Scan your passport to link your account to your identity and Google can provide the ZKP-equivalent verification to a third-party that you're a person without sharing your passport." -> They don't today

"Sign in with Google" would like to have a word with you." -> Email is shreyjaineth@gmail.com

Maybe I am missing something here but I don't understand your point? My argument was to state how interoperable identity today is seen in an elegant way with crypto wallets that let you attest to authenticity of your social interactions from one platform on another. Google could surely do this, but to my knowldege they do not today?

I made a typo: I mean to say Google *could* scan you passport, not can. That may clear up some confusion, and you're right that they currently don't. In some sense, there's no use speculating what Google might eventually do, but I think it's equally valid as speculating what alternatives to captchas Fortune 500 companies would switch to.

The logic goes:

1. Right now we can justifiably assume all text written is by a human, so no need to check identity ->

2. Models like GPT4 make that assumption invalid so we need some way to test for humanity ->

3. The most widespread identity checker right now are in web3

I agree with the first two points but dispute the third. I'm saying "Sign in with Google" is currently the most widespread identity checker (it's not trivially easy to make a Google account, you need a phone number and can't use a virtualized one) and if it went a little further and added passport verification it would also be comprehensive.

There are definitely some very elegant identity solutions in web3, I don't mean to diminish that, I'm just skeptical they'll be able to beat "Sign in with Google"s distribution and feature parity with the passport thing.
