I didn't oversimplify anything. I only showed that jobs come and then vanish. With each improvement in technology, there's no room for certain jobs. You have two options. Prevent the improvement of technology to keep jobs being vanished, or enforce it and accept the current situation.
I simply said: Either you say we don't need CT Scan and MRI, or you accept the disappearance of Pneumoencephalography Technicians. You can't have both.
I think at this stage, AI is inevitable. No one can stop it anymore. The question is not : "Is it necessary?".
The real question is: Will we adapt the world to that reality, or let it happen without a plan?
