It's a memoisation [0] problem: how completely does a professional store effort-expensive, intermediate results?

Doctors and nurses, who also deal with complex systems, have gotten exceedingly good at this with charting.

We? Considerably less so. But I'd hazard improving every year.

Reduction of boilerplate and flexibility-for-the-sake-of-flexibility in languages has been a big win, IMHO.
