If you want job security, work at a defense company. Pay would suck, the bureaucracy would drive a lot of people mad, and you would have a lot of not technical people running the show that might infuriate you (PMs), and there would be ridiculous amount of six sigma processes and other mental masturbatory exercises to make bean counters happy…but hey, you want job security….
And you might even be able to work on the latest coolest killing machines.!!!
