The problem is, in the limit, more productivity growth means robots (I actually mean cybernetic being), and robots will put more humans out of traditional work. I can easily see 75% unemployment by 2075.Good article, but I disagree with "economic growth is what we actually need". Imo we need productivity growth, and we need a redistribution (I'm not saying how) of ownership of that productivity growth. Economic growth and productivity have a relationship of course, but differ in at least one important way: economic growth alone will lead to more environmental decay.
I agree that if you have some sort of UBI, with robots, it can work.
