We had computers since the 30's (before even), and software since the 60's.
Which very pretty much statistically insignificant.
Not really. If your business designs bridges or planes, a single computer in the 60's would replace an entire army of mathematicians, physicists, architects, and accountants. We used to have large rooms, filled with large plotting tables, with tons of people using sketching tools and slide rules to sketch out design mechanical drafts by hand, calculate forces on each part, track to make sure parts fit, double-check the math involved by hand, etc, and now in the 60's all that could be replaced with just a few people writing programs for the computer to run hundreds of simulations a second. Where did all those people with math skills go to? There is no need for them, now that computers can do all the math automatically.
We also had factory automation since at least the middle of the last century,
You are mistaking mechanization with automation.
I am not, actually. We could replace people picking up bottles and corking them by hand, with a machine that would automatically grab a bottle cap and stick it on top of a bottle as it went by. Fully automated, no computers needed, and tons of corkers out of jobs.
Unless by "automation" you mean "artificial inteligence," to which I would say stop moving the goal posts.
You are basically claiming that a tractor or a machine replacing 25 farmers or factory workers with 1 is not a problem, but a computer replacing 25 tractor drivers with 1 computer operator is. I don't buy it.
It is really that difficult to comprehend that this time those 24 have absolutely nowhere to go.
Yes, it is. Is it really that difficult to comprehend that we didn't even know about internal combustion engines in the 1800's, or about computers in the early 1900's, or the internet in the early 1990's? Because a lot of incredibly brilliant people could not predict such technologies arising and creating tons of new specialized jobs, I am not going to trust some unknown guy on the internet making predictions that no such new technologies will come to exist in the future.
As i said your approach is faith based that magically new jobs will come out of the woodwork in enough quantity.
I dont care if there will be jobs for 10 people. Free market can't operate like that sorry.
We still have jobs that pay people to remove staples and paper clips from documents before scanning them. There will always be jobs, no matter how high tech we get.
Beside if you actually study history machine replacing 25 farmers or factory workers with 1 was actually a problem for those being replaced. Luckily for the system change was done slowly within decades people had time to adapt. Today drastic changes are within a years
You can't replace creativity (not yet). So, sure, it was a problem for the farmers, but they found something else. Sure, computer design was a problem for mathematicians and plotters, but they also found something else. New computer languages that keep changing and improving every few years, but computer programmers just keep learning new syntax and keep up with the change. I imagine in the future, you won't be able to have a job where you leark a skill, and spend the rest of your life doing what you learned (like you could when working at factory assembly lines), and everyone will have to continuously learn on the job.
Take the 3D printed gun example someone brought up. You could collaborate on a project like that, with someone being an expert in handle grips, having spent time studying them, and continuing to learn more about them by printing prototypes and checking how they feel. You could have an expert in structural design tweaking and improving the strength of the barel. You could have a mechanics expert, tweaking and improving the firing mechanism by making it put out more force with less trigger pressure. And then all of them can continue to use and improve those skills as they design newer, better, more efficient and high tech guns. So, instead of people working on a project for one or two years, and us buying products, like a new version of an iPhone, every one or two years, you would have new and improved products coming out every month, then every day, then pretty much continuously, whenever you have time to hit "Update."
