Haven’t met any that stops growing, what many do though is focus more on the business side and less on the coding, because it’s easier to get money that way. Starting freelancing with their own tax schemes, becoming a power point knight, short IT architect stints.

When you are young you want to dazzle people with your own projects, when you get old you want to have money enough that you get time to dazzle people.

But in the end we never really dazzle people like we did when coding young, because we want to make younglings to feel encouragement, especially before college.
