I disagree. Many times coding is input constrained—common refactoring patterns are one obvious example. You enter a pattern of tight input-evaluate-respond-repeat loops where you evaluate the refactoring change at every location where the text would also change. Very few problems worth solving can be solved without a better editor than pen and paper, and thought controlled ast aware editors are the logical conclusion of that. Hard problems would not be better aided by better input. In my experience, very few money making products deal with hard problems, just boring problems.
