Earlier quoted context omitted.
Driving the equipment around is the fun part, but not the real work that goes into the business. Farming is actually quite challenging. A recent problem I remember having on my farm: Soil is full of wet lumps of clay, unsuitable for planting, cultivators are not breaking them up and you have a few day window to fix the problem before it gets too late into the season to plant the crop. What do you do? I actually agree…
Honestly, that sounds to me like "Oh, god. What would happen if everyone could drive?" Er, people would have more individual choice. But we would still need buses and stuff anyway. (And you will always have some non-drivers.)
However, the previous poster suggested that there is no need for more professional farmers, so there is no need to teach farming. By extension, he seems to be saying that when we have enough programmers in industry, there will be no need to teach programming anymore.
And pushing people into an industry does come with dangers. When I was a student we were pushed into teaching. Today, I have friends who went with that push and are still on the job hunt many years later because so many others did the same.
