Programming

I would be torn between Python and Rust.

The case for Python is that I'm already very experienced in it (nearly 20 years), there's a good job market out there for it, and the ecosystem is one of the best in existence. It's like a comfortable well made jacket, maybe a tad worn in some areas but very functional. And it's not standing still, with a community that's committed to constant improvement.

Rust is more fun. I like the way it's been put together. It can also be used in more areas. There are some niches (wasm, low level, kernel) where Python just doesn't work. It has been able to benefit from the years of mistakes from Python and other languages on things like how it handles Unicode strings. I don't know it as well as Python, but I barely get a chance to work with it so that could change quickly in time.

I don't really want to do everything in one language but if I did have to pick it would probably be Julia. It's slightly simpler than Python, and significantly faster without relying on APIs written in C. And has some really great features like broadcasting, multiple dispatch, and a good type system. The only place I feel like Python has it beat is quantity of libraries and support network, which both basically come from the same origin of just having more users. I'm hoping more data science types switch over in the next few years, since Julia is already great for most things mathematical. And I hope that momentum allows Julia to perhaps reach out to other domains.

Rust, hands down.

Clojure, can't stop using it, so fun to use!

Ruby. It’s designed for developer happiness, and it’s beautiful. Not as beautiful as it once was, but still lovely to code in.

Go. Nothing strikes a balance of ease and performance like go

DNA

Definitely lolcode.. HAI Can Has stdio KTHXBYE :)

Go or Rust

Clojure. Simple language for complex things. It also has java interop and Javascript interop and c# interop. So I will be fine.

C. I've been programming for over 30 years and it's the only language to survive. Imagine if I was asked this question 30 years ago and picked perl or Pascal, I'd be screwed today.

JavaScript because you can do everything with it and long term all other languages will, most likely, gradually fade away (except for C/C++).

I'm surprised no one has picked either macro assembly on their favorite ISA or, perhaps just to screw with people, Forth.

JavaScript
