Has anyone considered the possibility that maybe the workhorse technologies in software development have begun to stabilize? C, C++, SQL, Unix etc. has been around for some time. Java and .Net aren't going to go away anytime soon. We may yet see some disruptive changes in Web development, but I doubt whether the basic Javascript/HTML/CSS scheme, or PHP/Python/Ruby set will become obsolete anytime soon. My plan is to ensure that I can always deliver valuable software and maybe even create some that I can own. A lot of my friends are doing their MBAs - I just don't think that route is for me.
