There is a better reason not to ask the kid about his or her future occupation.
The job might not be available in future. Take the example of the army. It is tempting to think that soldier is still the same. Until you realized that if the soldier carries a new equipment, it is going to need a repair person. Or a specialist to operate it.
I recalled this mind-blowing moment when I was asked to load a generator on a truck in a military exercise. I asked what equipment was going to use the generator since most of our electrical equipment were battery operated. I was informed computers. In the truck I saw a fan and asked if the fan was supposed to cool the computer operator. I was informed that the fan was meant for the computers as they overheat.
One day, soldier might mean the human charging the robots and repairing them. A clinic or hospital may not have a human staffing it.
