I can't speak for the other guy, but as a person who manages humans at work: I'd rather have a robot at home.

1) I live way, way out in the middle of nowhere.

2) Humans are fickle, late, emotional. They have requirements in their own life that conflict with the jobs I want them to do.

3) Taxes. I don't want to deal with this headache. 1099 my cleaner or whatever?

4) In my version, the costs of owning the robot are less than the costs of hiring humans. If that wasn't true, then I'd reconsider. I probably wouldn't buy one until the cost switched like that, unless maybe it was open-source or something.

Here's another way to think about it: Amazon is willing to pay workers to do the job, but they'd obviously rather have the robots do it. The robots work close to free, don't complain, and probably do a better job (at the jobs they're capable of). Why wouldn't they hire a human for that? A lot of the same reasons.
