We're going to have two phones, the big brother phone you usually leave at home for banking apps and tax filing and boring stuff like that, locked down and nanny up, and the "real phone" from aliexpress or whatever that is purchased rooted and you actually live your real life upon.

I would not be surprised to see double sided phone cases so we can carry our big brother phone with our real phone.

There is some prior art in people being forced to carry a "work phone" and a "personal phone" at the same time.

There will be strange product marketing effects. If you only carry one phone, you can currently talk people into spending over $1K on a high tier big brother phone. But if you only use a big brother phone for bank apps and only at home, a $1K phone from Apple or Samsung is a hard sell, I'd be more likely to spend $1K on a really nice anti big brother phone on ali express or whatever.
