Do managers write daily? If so my conjecture is they should code daily. Will they write a UI button. No. But I am not sure that's what a typical coder should be doing in a "programmable company". I am really finding it hard to express this conjecture (it might be rubbish) but why should humans be involved in day to day creativity in the operations of a company? Is it possible at some point to have the operations of a company encoded, moving along and fixed? This is the ideal anyway (the whole point of "change management" is improvements ). Anyway, my conjecture is that there become three basic management functions - monitoring the company, modelling the company and mentoring the people. I can easily imagine code written to explore new models (it's what everyone does pouring over excel all day - in fact I would suggest a company that can do away with excel from managers is winning)
