Go is relatively easy to learn, and the semantics of the language make it more difficult to write "clever" code that's difficult to understand.

That's the main selling point, with a secondary point that it statically compiles so you don't have to do a whole Python/JS distribution thing for CLIs.

Java feels like the closest contender here, although it really sucks for CLIs due to start up times. I don't think it's the easiest to learn either, but I've never tried all that hard.

It only really makes sense to me at org-scale, though. I think you raise a very good point for individual projects, I too normally don't choose Go for that (unless I need compilation to make distribution to myself easier on corporate laptops).

Java has GraalVM which compiles to native code if you care about startup time.
