Been using zen for the last month or so and it has been pretty good. I went from using super locked down librewolf to using zen. It is not as private by default but can still be tighten down and with proper support for profiles you can compartmentalize it.

It does break and change a lot since it is in alpha but I used to be an arch user so honestly it doesn’t bother me too much.

From what I understand his initial reveal of the Tesla robots did have a human in a bot costume dance on stage which is why some people assumed it was the same situation with the more recent demonstration. That demo was remotely controlled as you said.
