I have mixed thoughts on the elimination of human workers. Problem to me is the really unskilled workers. They were able at one time to go into fast food as a last resort, but the raising of salaries to $15 per hour has caused FF companies to run leaner and have employees constantly doing more. Our local FF places, you can tell they've done that. No one has a minute where they're not doing something. The US has the largest number of employed people ever right now. Black women are starting small businesses at a record rate, as are all other categories. So I think the future will be filled with contract work where people work with, not in, large corporations. People with high quality skills will do great.
Somewhere I read a piece that said in the future that all people will have to become capitalists and find ways to generate revenue by investing money or their work effort. I'm not worried about this, however, because every machine we install also requires setup, care, maintenance, repair, tweaking, programming and eventually, recycling. All of those are work for humans. The tricky part to me is the 3 billion people with no education, skills or opportunity in the emerging nations and Less Developed Countries (LDCs). In some places, there will be opportunities, in others, not so much. For the low end, I foresee lots of jobs for soldiers.
The more I do, the less I accomplish.
