I wasn’t meaning to be factual about the 3:1, other than that every bit of automation is going to make jobs disappear and the number of new jobs will be less in number. It’s a net loss of jobs, over the long term.
I believe in increasing productivity, but I think philosophically, we should be keeping people at every juncture point. There shouldn’t be time when we don’t end up having to deal with a real person to have our needs met. Just because a little bit of automation is positive, doesn’t mean 100% automation, potential, is a lot better in my view.
We humans tend to think in terms of extremes. We aren’t very good at moderation and keeping our philosophies where they work. If I read my Bible correctly, we should be moderate in all things, to which I include automation.
I suppose wars will take care of that “surplus population”.
