Oddly enough, I find programming to move at a glacial pace. 10 years ago I thought it was a fast moving field, but I keep seeing the same ideas remixed over and over. If anything I think programmers should think like musicians at the beginning it seems like things are constantly changing. But, that's all superficial changes in style over time, after a while you focus on the ideas and it takes less time to keep up with trends because you have seen those ideas before.

PS: That and Google let's you leverage a lot of deep knowledge once you understand how to ask.
