The thing is as I get older I realize that languages are pretty much all the same. They sort of break into two distinct families, those based on C and those based on Lisp (or secretly lisp, at least, I'm looking at you Elixir). Once you have sufficient experience with either of the families you'll be able to pick up any derivative of that family in a quite short time.
I don't know how much of this is due to the fact that I'm also entirely in the Apple ecosystem bubble, I'm sure quite some of it is due to that, but hey, live and let live. Oh and, I'll have a iOS app coming out soon, so that's cool because it will be my first one. Not my first attempt, but hopefully the first one to actually land in the App Store.
