What an excellent, level headed article. I wish it'd be emphasized a little more - as a software dev, you'll likely either end up having to move laterally to a new skill set that isn't entirely related to your previous experience (moving from C++ to Ruby on Rails and web dev as the example in the article) or move 'up' to management or architect positions. Both of those are difficult and fairly unique to software development. Most jobs don't require these types of shifts. A number of jobs do simply wear your body out and leave you in difficulty in your 40s however, and that requires a complete career shift or that move 'up' to management, both of which are non-trivial paths to take.
