> What would the half-life of the value of a software engineer’s knowledge be? I suspect it’s somewhere between the physicist’s and the English professor’s because a software engineer’s knowledge is a combination of eternal computer science/engineering principles and ephemeral technologies that drift in and out of popularity over time. Isn’t most of a physicist’s knowledge eternal, relative to a software engineer’s? After all, software engineering is based on systems designed by man while physics is modeling the fundamental universe.
