Sure - and from that perspective farming was a probably not a great example. But surely more people could be programmers than currently are. Pushing a car is physically exhausting but doesn't require much training and practice. Programming requires training and practice, but I don't know that it requires more training and practice than, say, becoming a lawyer, doctor, martial artist, or other engineer. And the opportunities for practice come much earlier in programming training than lawyer or doctor training! Though now that I think about it, farming involved more than just physically exhausting work - knowing what to plant, when, how to handle the soil, etc. - those all seem "hard" to me in a "training and practice" sense.
