People will still pay for convenience or functionality.

If there is a feature that cannot be done on-device, and that on-Internet feature can be effectively moated and duplication-resisted, then if it’s a feature that people think they need they will absolutely open their wallets to pay for.

The trick is finding that feature or attribute that cannot be done on-device, and then moating it against AI duplication. Do that, make it appear indispensable in the minds of people, and they will absolutely pay for it.
