In such a future the iPhone and android ecosystem is dead? Because a single $1k phone is a hell of a computer. So if you can still buy a phone you can still get a computer. Local AI aside these are very capable.
iOS is apparently going to have mandatory age gating, so likely that will come to Android as well.
Maybe we’ll finally get some good tools to make real productive work possible on phones.
You don’t really own an iPhone in terms of being a computer. It’s different for certain Android phones where you can install a custom OS. Those are also less powerful, however.
