These comments about replacing humans in childrens lives can only come from people detach from reality. The essential part of a childs early life is connection with adults.
Its on the same level as the rich pushing for more people to have children. They outsource their own childrens care to others so having more kids has little to no impact on their lives.
Although not as aggravating as sand in sensitive crevices, doing it laying or kneeling on a hard floor (stone, tile or wood) is very uncomfortable.
