One drawback of Go (in my opinion) is that it has a runtime. So it's very difficult (impossible) to use it with other languages that also have a runtime. So if you learn Go, you'll never be able to use it to interoperate with e.g. your Python program to speed it up.

With Rust, you could use it to replace the most time critical parts of your high-level program piece by piece. The learning curve is then much easier, and adoption can be gradual.

Never done it myself, but:

Having a runtime does not, by itself, preclude interoperating with other languages that have their own runtime. Here's a project that does that for .NET and Python:

http://pythonnet.github.io/

(Note that this is not a reimplementation of Python on top of CLR, but rather a bridge between CLR and CPython.)

The thing that makes FFI problematic in Go is green threads, which have their own stacks that nothing but Go understands. Thus, every FFI call has to arrange things to be what the callee expects, and you can't do async using goroutines across language boundaries (whereas callback-based solutions like promises work jsut fine).
