> Developers do need to pick a set of core technologies, and stick to it or a career can fall apart I bet

I hope not for my sake :) Im currently contracting writing C++, but my previous contract was with the ASP.Net stack. Before that I was working on a lot of Java services (introduced Scala to good effect)

I also have started a side business helping small companies by making small apps helping with their everyday stuff - sometimes Ill make iPad apps with Swift, but more recently Qt/QML to make something that runs on both OSX and Windows desktops natively. I also made (very small!) web apps for them hosted on both Azure (MS stack) and AWS (linux stack)

After a while learning the core aspects of a new language doesn't take very long, and they generally have to address the same high-level concerns. That said, learning iOS development was a continual hassle but feels like it was worth it to have a native app that I can deploy easily using HockeyApp etc.

edit: I will undermine my whole point here by saying that I abandoned a personal Android project because the dev environment felt so ad-hoc and duct-taped. I spent a ridiculous amount of time trying to get the simulator to render GL properly without any luck (on Windows)
