Python - ok, but Rust? How many Rust jobs do you see posted on major job sites?

I always find this logic a little troublesome; there are certainly many more Python jobs than Rust, but there are also many more Python programmers than Rust programmers. Wouldn't it make sense to optimize for the best ratio of available jobs to qualified applicants rather than just the largest number of available jobs? (I'm not saying that the ratio is better for Rust, just that the metric itself being used seems flawed).

Of course, there are also reasons to learn a programming language beyond job listings; GP might work on things that don't require a specific language, be looking for a language for dude projects, or just want to learn a language for fun.

Python will get you a job today, but Rust may well be more valuable in the future. Or it may be a flash in the pan that never catches on in a big way. The future is hard to predict.
