Since Oracle is trying to kill Java right now, what should my next big love be?
Maybe C#?
Any suggestions?

Kotlin, it's better anyways. Kotlin + OpenJDK + OpenJFX, and no worries're left.

This reminds me the time my old boss tried to keep me from quitting suggesting that C# is a dead language and I was going to learn a technology doomed to fail. Proposing me to work on an internal project done with Java. Fuck that guy. I'm super happy with my new company's stack.

I mean, as someone who made the switch to C# when I started working, NET Core especially is great to work with. Can't in all honesty say it makes sense to jump ship like that though.

Rust, Haskell, Lisp (Clojure or Common Lisp), C, Kotlin, Javascript

The possibilities are endless
