Identity is next. I think they'll start tying your Google, Apple, etc. account back to your real world ID. It'll be opt-in and they'll give some kind of sucker's reward for it like reduced captchas. It'll be sold to the public with the insinuation the "good guys" use verified IDs and the "bad guys" don't.

Yep. Auth, identity, etc. are going to get sucked up by big tech and even after it happens we'll have people on HN telling us how awesome it is that we don't have any control over our digital lives because Google, Apple, etc. are "protecting" us. Case in point, the iOS app store.
Passwordless tied back to biometrics is their endgame IMO.
