Worth buying? Maybe.

Actually bought and distributed? No.

Again, hardware just doesn't roll out that fast, and you're talking about trying to distribute expensive hardware to a population with a 47k median yearly wage.

I've built robots. Even if the software expense is ~$0... you're not going to escape the fact that a robot that can do anything remotely similar to household work is just going to be expensive. Like, several thousand dollars in actuators and sensors alone, not counting any compute.

LLMs are a SaaS - Robots are delivered hardware. The graveyard is littered with software folks who thought they could deliver hardware like it was software.
