>What would you use it for that other machines are unsuitable for?

The thing I love about the tech culture in China is that they never really seem to ask themselves this question. They just do cool things because they seem cool. See their EV market for more of this. A car with a movie projector for headlights? Why not? Wish we had more of that in the US.

Meta ray bans and evtol drone taxis and waymos... we've got plenty of cool stuff in the US that's cool and question.
