I don't think the CapEx of a robot barber would work out, no matter how low the OpEx. (Which is why we don't see very many non-humanoid, pre-programmed robot barbers, either.) Just because the tech would be there, doesn't mean it'd be practical/affordable for mass deployment. It'd likely be the domain of rich people and/or tech companies—just as less-complex telepresence robots are today. And by the time the CapEx would get low enough to use telepresence for such things, we'd probably have the general strategic AI to not need it.
