Also, profiling applications is surprisingly easy to learn. It boils down to looking at timestamps, and seeing what takes the longest. The majority of the effort is just figuring out where/how to get the timestamps you are looking for. I will add that I think software complexity is only going to continue increasing over the long term; it reduces in some domains, but expands in others as we develop more advanced systems. Some kind of analogy to entropy.
