Well, what I wanted to say was that the "craft", i.e. skills learned when working on a real project with experienced developers, is something I use all the time. Academic knowledge less so. Take, for example, complexity theory. I use that once a day or even less. And in 95% of those cases I could just consult a simple cheat sheet (stuff like "sorting is O(n log n)").
