I always understood this to be why Tesla started working on humanoid robots
As soon as Waymo's massive robotaxi lead became undeniable, he pivoted to from robotaxis to humanoid robots.
The key question is whether general purpose robots can outcompete on sheer economies of scale alone.
Purpose built, that probably takes the form of a humanoid robot since all of tasks it needs to do were previously designed for humanoids.
Dusting with a single extensible and multiple degrees of freedom arm would be much more maneuverable than a human arm.
Loading and unloading washing machines or dryers or doign the same for dishes and cutlery in a dishwasher is not inherently designed for humans.
If anything, selling an integrated "housekeeping" system that fits into an existing laundry and combines features would be a much better approach.
For old/retrofit renovations it also makes sense, but otherwise, yes, a human-form robot makes sense.
The question is which is a better investment for any robot manufacturer in 2026?
I wonder how long they'll be closed for "modifications" and whether the Optimus Prime robot factories will go into production before the "Trump Kennedy Center" is reopened after its "renovations".
