Generally, the tech side is one-level-removed. A lot of tech-work involves providing for people... who interact with other people who are experiencing the "real" problems.
Don't get me wrong, it's valuable work (and boundaries can blur) but it's like the difference between... a lawyer and a social worker. Or a bridge-builder versus a traffic planner.
At any rate, less "You came to me for help in achieving legal goals X, Y, Z" and more "the civil-rights organization has hired me on your behalf".
I agree, but the key point in there is that applying new tech often requires significant domain-knowledge in whatever that other industry is.
Generally, this means chains of people, rather than just one person who happens to be both a professional programmer and professional <other thing>.
* In the American sense. In the European sense, this term is often used to denote the design of interactive experiences, which is quite different.
