Go is awesome and has great ecosystem. I think if you want to just deliver Go is one of the best language out there. Of course as long as the project makes sense(I.e no client side/GUI stuff, there it gets messy)

If Go is a junior developer onboarding language, then I proclaim myself a perpetual onboarding junior.

It's no wonder then that Google used to be all in on Python in the 2000s as a language for juniors and then invented another language with similar users in mind. With AI becoming what it is they probably did not need to do the latter.

Python owes a lot to that initialish Google push where for a few years you couldn't get a job at google without knowing python or you could easily get a job if you knew python. Maybe both.
