"Your job screwing bolts on cars disappeared? Learn to code and be a programmer." Great advice for the typical HN reader, but a lot of people who can learn to screw bolts on cars just don't have what it takes to be a good coder. I don't know if it's due to innate intelligence, upbringing, environment, attitude, or what. But there are millions of people out there who just don't seem to be able to master the abstract thinking required. And I'm not sure they'll ever be able to, regardless of how much education we give them. What should our economy do with those people going forward? For social stability and ethical reasons, we ought to give them a path to decent middle class lives. How do we make that happen? I think the key's that from 1880 to 1980, we invented mainly technologies that pulled more and more people into the labor force. Now we've started inventing technologies that push more and more people out of the labor force. How do we reverse the trend? What kind of technology can we try to invent that pulls in a huge number of people to work, the more laborers, the better?
