The practical problems with robots are effectiveness, cost and safety in roughly equal parts.
Take the recent anti-Flock actions - it’s probably mostly not ‘internet people’ going for evening walks with their angle grinders. Everyone starts to care about privacy when it really becomes invasive.
Likewise, people might be fine getting their elderly parents a robot to help out with household tasks, until intimate stolen videos start appearing on realgrannies.com or similar.
It's very obvious that there is a difference between a single person that you can personally vet, and something that records videos that can be shared anywhere.
> I think internet people care about some theoretical surveillance angle more then anyone else actually does.
Yes, that's usually the case. However in the very current time of surveillance resistance with the de-Flock movement, I think there is increased mainstream awareness of the issue.
