Earlier quoted context omitted.
Everything that everyone works on affects people. Programming is no different than any other profession in that regard.
That's obviously not true, as there are major differences between professions. The work of an architect or event planner affects people directly and intimately in everyday interactions. The work of a mathematician or sociologist doesn't. Programmers' work is closer to the former group, but educational and hiring practices pretend it's more like the latter.
This opposed to analysts, marketing who directly engage with clients and management who interact with their own group as well as at least people they manage.
