I get that sense too. Probably does work awesome if you're inside. But man it's a mess when they externalize stuff. Just one example: their cloud platform CLI includes an entire python installation and takes 1.7G on disk, just to make API calls...
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...
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.
For anything more advanced they offer language specific SDKs in Rust, Swift, Kolton, etc…
For example integrating storage in an iOS app.
