I was about to write something similar. The TLDR that I tell people is computers do exactly what I tell them, people not so much.

In IC work there's often a 'right' answer. At least an answer that can be tested and pass some sort of test. Management is murky, "will this deal work out?", "why are employee A and B constantly fighting?", "partner is asking when X will be done, that I'm only tangentially in control of" ugh, the list goes on.
