Just like the Industrial Revolution.
Surely ATMs and online banking have already done that? Bank branches close with scary regularity these days, the banks themselves must be shedding staff more than any other business. I'm sure more people get employed in their IT departments but I can't imagine it makes up for all the losses in branches. 40 years ago I used to visit the bank at least once a week, sometimes two or three times, but I have not set foot in a branch now for many years. There is no longer any need. That's a lot of people whose jobs are no longer relevant.I will give you an example on a domain I know well: banking.
As an IT, since 20+ years my job has been to:
1 - smoothen the client experience (20% of the effort).
2 - reduce the bank operating cost. (80% of the effort).
To be clear, point 2 is nothing less than replacing human job by automation.
Why would anyone be nervous? You can't possibly think AI would do a worse job than people of running the place? Look at the f**king clowns we've got in governments all over the world today. It's a sad and sorry lot, a computer would undoubtedly do a better job.
You have to remember that AI doesn't think, it relies on its ability to store and process data at a much higher rate than we can to give the impression of thinking, but it's all still just algorithms. It's not self-aware and it's highly unlikely it ever could be so it's never going to outgrow us.
That only works if people are aware of history but these days people seem less and less concerned with esoteric knowledge like that.
Oh, I have hope but you wouldn't like what it is I hope for.have hope
Whilst we are stuck on this tiny planet, resources will always be finite. Automation costs money, the machines to do the work don't just drop from the sky, there has to be a whole industry building and maintaining them and that industry requires resources. Technologies like nano-assembly might one day make better use of resources but resources will likely be finite for a few centuries yet.
