Career wise, you should pick up popular languages, Java&#x2F;C#&#x2F;Python&#x2F;Ruby&#x2F;JavaScript.<p>Between Go and Rust, I think you should pick Go because there are a significant number of developers from Python&#x2F;Ruby&#x2F;JavaScript enjoying programming Go. Many startups start using Go[1] and couple of universities use Go in their classes[2]. Rust targets system development primarily occupied by C&#x2F;C++ developers. Many still prefer C++ and I rarely see Rust job.<p>[1] <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10822019" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10822019</a><p>[2] <a href="https:&#x2F;&#x2F;github.com&#x2F;golang&#x2F;go&#x2F;wiki&#x2F;Courses" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;golang&#x2F;go&#x2F;wiki&#x2F;Courses</a><p>Edit: I may be biased since I enjoy programming in Go.
