The flip style ones are pretty useless other than getting a preview on the main cameras.
The fold style, especially a trifold, seems pretty useful, and lets you basically carry around a decent size tablet in your pocket.
I definitely wouldn’t call it a gimmick, although the price and durability tradeoffs are nowhere near worth it for 99% of people.
Laws vary around the world, but I think at a minimum, you’d need a court ruling that aliens / AIs are people.
