If you already have a job and you don't want a new job neither on the short-term or long-term, you could:

- choose Go because: - it is easy to learn - it is fun - it is productive - it has good performance - it has good maintainability

Or you can:

- choose Rust if: - you have the time to learn the ins and outs - you have time to keep up with the never ending new features - you have interest in write software that is usually written in C or C++

What you need to have in mind is that both languages have benefits and trade-offs.

Go for example is easy to learn because is a small language but because of that you will need to write more code. Modern developers are usually averse to write lots of code. But write the amount of code that Go requires you to write will make you think better about what you are writing and at the end this will make you a better developer.

Rust takes time to learn and features keep bubbling up from time to time and some times development with Rust can be slow compared to other languages, but it is an excellent replacement for C or C++ if you are writing software for a supported architecture, because you will have the C/C++ performance without lots of bugs related to manual memory management.

Another thing to keep in mind is not to use Go or Rust when you should not use them. For example, you will see a lot of people using Rust for the sake of using Rust just because Rust is "memory safe", but Go is "memory safe" too; the difference is Go is garbage collected and Rust is not.

If you can afford a garbage collector in the software you are writing, don't waste your time with Rust if the software domain is one that Go excels, like networking programming.

But don't use Go for the sake of using Go as many people do, for example, trying to replace C or C++ with Go, because Go is not a replacement for C and C++.
