We're luckily seeing an increase in the independence of phone numbers as 2FA options. A lot of professional services / work-related use an app or TOTP now so my reliance on a phone number ended about a year ago.

I would feel like in the far future phone numbers would be obsolete and be replaced with different system, but cellular networks suck in making any meaningful progression so I'll likely be dead before something like that happens.

Unfortunately cutting out a few of those systems will severly impact my social life and the tradeoff is not worth it. I could get a second phone maybe
