Go in particular, you can get up to speed so quickly.

Oh my goodness yes. Amazing language. I grew up on C (and to a lesser extent C++). Go was so wonderfully easy to learn. I picked up the basics in literally an evening, and was making useful utilities in a weekend. The memory safety, static typing, easy and true concurrency, massive standard library, the fact that it is a compiled language that outputs a static binary and doesn't depend on the destination machine having the exact same interpreter version and imported packages as your dev machine, I love it. It is a headache-preventing language. I still write a little C++ but just for microcontroller projects, things using Arduinos or ESP32's and the like.

I've got issues with using dynamically-typed languages for anything but the most basic scripting tasks. You just don't know when the whole thing is going to fail catastrophically on weird inputs.
