> And it would seem to make sense once there is no need for human attendants, nor any potential accommodation for them.

Perhaps it could be combined with a back massage. Those chairs that you stick your face in would be tailor-made for this!

That's exactly what I was thinking, you can lay face down on a massage bed for a pretty long time, so they should just be able to put the robot in your mouth through the face hole lol

I imagine, particularly with V1, there's probably going to be human attendants for a good portion of the procedure. You'd want them for administering the numbing agent and positioning the machine for the procedure.
