Yep I get your point clearly. Although I like to believe people should change domain of application if they want to. I think one can keep learning his whole life (only if he wants too, obviously).
I’m very strong on that feeling, cause you see I’ve been working on search engine, websites, desktop apps, client-server stuff and other headache-kinda-things, and since I’m a kid I always wanted to make games (my first coding at 12 was a game btw). Took me 20 years before I made the decision. So yeah I guess I want to shout out: do it if you want it, won’t be easy, but just go for it.
