Or is just a specialization choice. Taxi drivers don't care how a car works, they hire a mechanic for that. Doctors don't care how a catscan works they just care that it provides the data they need in a useful format.

This analogy baffles me. I don't think anybody here is making the argument that we must know how all of our tools work at a infinitesimally fundamental level. Rather, I think software is an endless playground and refuge for people who like to make their own flavours of magic for the sake of magic.

I like the definition of magic I learned from Penn Jillette, (paraphrased): magic is just someone spending way more resources to produce the result than you expected.
