Interesting and important discussion at the heart of some very basic economic beliefs about how the world works.
Because it is so dramatic, the implications for FIRE are legion...potentially making it easier or creating an economic environment where it is nye on impossible to retire with a great standard of living.
My $0.02:
Automation will be super impactful and result in massive destruction of classes of jobs but the attendant creation of whole new classes of higher value jobs. We've seen this movie before. When I started working there was actually a group of people who's job it was to create fancy charts for exec presentations. The exec explained or drew what they wanted and someone in chart creation team worked on it, passing revs back and forth. Powerpoint nuked those jobs out of existence but now we can afford to do high quality internal video productions with professional designers, etc.
This next turn of the productivity wrench will do the same in many places. When it's over, we will have more people working in more rewarding jobs and a larger economy.
UBI would be the greatest economic mistake possible. It risks the ultimate "tragedy of the commons" where people decide the best way to improve their lives is to elect people who agree to bump the monthly stipend.
I think it would then turn into the greatest mental health crisis in history. There is something very fundamental about having a constructive purpose to your daily life. Most people on this board who seek to remove work from their mix have actually had a purpose every day when they got up. Telling 300M people they don't need to work is unlikely to end well. Buy Pfizer stock and go long.
The intersection of the above is the educational system and our cultural instincts for education. Rather than putting $5T into UBI, let's put $5T into our education system to prepare kids for an automated world and ensure our culture supports it.
DD2 is interested in Nueroscience and programming. Spot on for a post-automation, high intellect, high value job. That's a by-product of being in a good school district, with parents who value education, and an economic foundation that allows her to consider these pursuits for real. Lots of other kids are not in those circumstances.
Raise the bar on the education system, keep solidly upon well regulated capitalist footings, and the rest of this will sort itself out.
Great topic!
