I wonder how long it would take for a device like this to become normalized in the US.
I don't think it will proliferate anywhere in the world. Many an unusual invention have found life but couldn't find a place for themselves. One reason I can think of for this thing is that it's nowhere near the real kiss. Sure, it has kinetic response, but there's no texture, no moist, no head movement... no character. Why would you want to pay for something like that?
