What machine will replace the hygienist?This is so extensive today that even dental hygienist are looking at their career being marched to the guillotine. And whatever you build, printers can now basically do it as well. You have a job today, but if you were just getting started in the field today you may as end it now because tomorrow you will be replaced by a machine. It's going to happen, and not in the distant future.
There's is a highly skilled job with complexities
not amenable to automation.
But I suppose a robot could be programmed to
ask "Is it safe?".
