Why do you think the vast majority of people fail to see it like this? Guys like Musk obvious hype it up as he now has tied the valuation of the firms he owns and operates to this story.
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.
It makes sense if it's a one-off but there are better solutions.
Maybe it does make sense for small scale businesses that need just a little automation? Like a humanoid robot could restock shelves and do inventory in a grocery store at night, and you wouldn't need to retrofit anything to be able to do that.
Large scale factories seems like the wrong use case for humanoid robots.
Does the computer 'memory' behave identically like human memory? Of course not. Does it look like the 'memory' of a human? Again, of course not.
