Re: When you can train it to do the housework....
I've noted it was a joke BTW, but
House work would be too difficult as an early task, homes are varied with too many variables.
I don't like my socks in a ball for instance after washing, and my sink tap sometimes needs a gentle whack and yes i like walking around that "obstacle"
Much better in a more structured environment like a Amazon factory removing lots of (expensive) humans jobs.
Or Cleaning the streets (day in day out the same streets, walk through once and repeat!)
No need for them on checkouts since we are becoming more used to doing the checkout operators jobs ourselves , they could replace the Herder who tirelessly directs us at the supermarket away from the single checkout operator still working to the bank of "Self Service Checkouts" with a simple Robot though but would we listen to a mere machine.
I would listen to a "Herder" robot if it was backed up by a Human OR it was ED-209 from RoboCop
