Why are so many of these command-line tools/dashboards written in Go?
I haven't used Go much but I've gotten the impression that tooling is very good, it's easy to create a self-contained executable and startup time is low. All this while the language itself aims for simplicity and doesn't include a plethora of features rarely used or needed creating an almost python-like simplicity.
You can easily statically link most languages by passing switches to the linker.
Python like simplicity is a far stretch. Golang basically just C with co routines and some of the annoying syntax cleaned up.
