The difference once robots become sufficiently capable is that in the past, there were other jobs to jump to. Once robots can do almost all of the jobs, there won’t be.
Horse-drawn coach builders could jump to building bodies for cars. Typewriter manufacturers started making computers. And of course, anyone whose job became obsolete could go back to school and get training on a job that wasn’t.
But if machines are performing 80+ percent of the necessary jobs, that’s an awful lot of people looking for work in a market that mainly “hires” machines.
I’m with you - I embrace future tech too, including full automation of daily tasks. But with that enthusiasm has to come the recognition that it’s going to put a lot of people out of work.
The rational course for society to take would be to let the machines do the work while we do what we want - we don’t need to worry about money anymore because sufficient automation would bring us close to a scarcity-free society. After all, we no longer have to pay miners to dig the ore out, or foundry workers to smelt it, or factory workers to turn it into a car, or dealership employees to sell the car, or mechanics to fix the car and, hell, we don’t even have to drive the car anymore! Meanwhile farm labor is virtually free (yes, you have to buy the robot, but once you do, you don’t have to pay it), the labor to produce equipment and supplies for the farm is virtually free, repair robots will fix the farming robots for free, etc etc.
But history tells us that’s probably not what will happen.
Computers were supposed to reduce the workweek by at least half because we would become so much more efficient that we could get the work done in 20 or fewer hours per week. Instead what happened was that business owners wanted us to do twice as much work, or the same amount of work with half the workers. Or, increasingly common, do twice as much work with half the workers.
Given the choice between producing more output with less input and therefore making more money, or doing the thing that’s good for society, business will pick more money almost every time. There’s no particular reason to think that won’t happen once most jobs can be done by machines, and it’s something we need to be thinking about now rather than waiting around until the jobs are gone.
