Creating pseudo alternatives to human/animal interaction using low effort robots on a planet with 7 billion people is absolutely absurd as a solution to the problem. Children are already starting to live life staring at rectangles half the day. It's one step above hypermedication of children that's rampant in the US
- Those billions are busy doing other things. There is a time problem.
- Even families don't care enough to visit their kids and elderly parents, so there isn't a lot of willingness to take significant action. There is a what people are willing to pay (in terms of time, money, and/or resources) problem.
- The scale of the problem is enormous and humans don't scale. Are there even enough sociable people you could hire in the USA for this?
