I don't disagree with the general utility of humanoid (or other multipurpose) robots, just not in a factory setting.

I think automating stuff in the factory makes zero sense - its a controlled environment with purpose designed tooling where anything that makes sense to automate has been automated. All the extra work will only result in marginal gains.

It's automating the stuff that goes on outside of the factories - for example construction imo is about almost as labor intensive as it was a century ago, the marginal gains were offset by more complex building techniques and higher expectations.

Housing is also just about the most valuable thing that exists in every country.

Because so much infrastructure is in humanoid form. If you can make something that can manipulate two hands on arms that are positioned and moved like human arms, you could just put that torso into a lot of situations to replace a human without a lot of retooling. That's the dream I think.
