That was about my guess, too. I would’ve given a range of 40-60 percent.
Economists I believe are incorrect in that new, better jobs will arise to replace those being lost. I think we’ve reached an inflection point of that trend, and will need to greatly change how our economy operates or watch large numbers of people suffer and starve very soon.
It is not clear which choice we will make.
I’d also say that in 50 years, around 80 percent of jobs will be automated and no longer exist.
