Find me any robot in the world that can teach, wipe tears, stop fights, read stories with 57 different voices, remember the family names/situations of 26 5 year olds, catch vomit in their hands and get 26 little people ready for PE 3 times a week without it's hard drive exploding and I will happily retire at 40 and let the 'bots take over.
There are some jobs that simply can't be automated because of the sheer unpredictability of them. No two days in my school are ever the same and because of that, I'm unsure how it would be possible to programme AI to cope with so many little impulsive, weepy, outrageous lives in any kind of positive way.
You are massively missing the point! As a previous poster has pointed out if we don't need workers, why the hell would we need teachers-just what would you teach them?
A basic education to teach a rudimentary read and write function could easily be taught by today's computers, let alone ones in the future, so the "Teaching profession" would cease to exist as we know it, and would be replaced with the future equivalent of TA's to stop the kids from killing each other, and to mop up the sick.
The last thing the "powers that be" would want is an educated working class. Keep the masses uneducated, poor and controllable. Just as it was in the Industrial Revolution, and that was when we actually needed a massive working class.
(Conspiracy theory mode) The people who would get real education would all be from the upper and upper middle classes, to perpetuate the AI function ("the Robots") that would be a direct replacement for the working class, which would become a huge financial burden, rather than a necessity. The rich would get richer, the poor would get poorer, and the "poor" marker would move far higher up the social scale, as all middle management, and any sort of "Back Office" function could easily be replaced by AI. Some of today's professions (i.e Teaching, Insurance, Financial, Law) would either cease to exist as we know it, or drastically reduce the number of people working in those sectors, and even then, their role would be to "feed the monkeys" (The robots).
I don't think any job is safe. And just look how the world has changed in the last 30 years, and no-one predicted the real impact of the Internet, and the next 30 years will see just as much change-but very hard to predict. I just hope it doesn't go the way I am predicting.
