I have never understood why cloud providers seem to think it is OK to write their CLIs in Python. The AWS one is too, and the Azure one went from Node.js to Python some time ago.
Tldr: there’s multiple factors to consider here and it’s more interesting to understand the pressures that cause the decisions, especially if you want to try to create a world where different decisions are made.
Outside specific cases around machine learning, it’s really not: Go is that language. It’s not like each of those platforms doesn’t have to have a similar team that understand Go anyway (for their SDK), so they could save their customers the abject pain of Python dependency management by just writing their CLIs using it.
I wouldn't be surprised if it was version 2.7 too...
For anything more advanced they offer language specific SDKs in Rust, Swift, Kolton, etc…
For example integrating storage in an iOS app.
EXTREME predictability (e.g. as never ever using the system's libssl), in trade for huge binaries. They go pretty damn far in this: you won't catch a Google binary even using most of libc.
