I think this perspective is now demonstrably false. It was basically the defacto position of most roboticists until a few months back. But we've already seen the cost of humanoid robots fall precipitously (even without the kind of mass production that genuinely useful home and real world intelligence would bring).

Which seems more likely, that cheap humanoids will continue to improve in dexterity, battery life, strength etc. Leveraging the vast investment in research into real world task training. Or - that we'll redesign millions of everyday objects to fit the limitations of current task specific robots?

If you answer the latter, I've got a whole bunch of mid century quirky labour saving inventions in the back room I'd like to sell you.

It’s not demonstrated yet as we still have to see a robot (humanoid or not) doing mundane tasks in full autonomy, efficiently and convincingly.

It still looks inefficient to have a humanoid robot vacuum a house by using an ergonomic tool designed around the human body.
