I agree with all that

But what I'm saying is you need a human-scale robot good at moving human scale work pieces to their correct place. These will range in size from something like a screw to something like a human sized sheet

What shape does this better than a humanoid one?

You could specially design a bunch of arms that will remove a workpiece from one station to deliver to the next, but do you have any idea how hard that becomes? You have to design each one to do that specific job, and you're going to end up with a bunch of unique robots that all need to be maintained, and probably need their own backups in case they break

Everything we make is already human centric, it just does make sense to build humanoid robots. You can have one fleet that handles all of it, they're interchangable generalists. Ideally, they can even do maintenance

Yes, it's less efficient. Yes, specialist designs would be better at their job. But it is really, really hard to do full automation, and this is a shortcut to get there

And the humans move around them, guiding parts into place with mechanical assistance and doing the finer details, because it's really fucking hard to fully automate the process
