I think he's right about many things there: manufacturing jobs are leaving and not coming back. Automation is becoming more and more advanced, particularly if you factor advances in robotics and ml since 2006 or so.
Things move faster and average just doesn't seem to cut it when you can manufacture excellence. Hell, lawyers and doctors will be next, how about faux ai that can write simple web apps or come up with good designs? Give generative models a few more years to advance, we'll see how far fetched that is. Some people will get very rich from all that. But that wealth will go to those who control what amounts to the means of production and they'll be able to defend those means with patents. I guess workers could strike back in the day, good luck with that now, the little guy has even less negotiating power.
All this to say, I think these trends and the shift they bring are going to be the most fundamental shift in economic organization since the industrial revolution. Not sure what the answer is, but I'm concerned that those in power dont even recognize the issues (they're not "nerds", as they say.) Time will tell, but I'm not all that optimistic about the average joes out there.
PS I wish the answer was everyone will start their own business, but honestly I just don't think that will be practical.
