Yeah, I think you stress topics like I do. Anyway the stress you seem to have over exact sciences is that you lack practice and your regular chemists do not know how to solve Schrödinger's equation.. it is nice to know the background but mostly useless (unless you fancy it in your expertise) so they just use the results that gives electron configurations and stuff... and it is lots of boring math. So general understanding is more important than technical skills as it might be other way around in programming where technical skills are more important.
