swiss tables were invented by engineers working at google's zurich office, hence the name
im surprised that go, a programming language also from google, wasn't using them!
for an excellent talk on the development of swiss tables i highly recommend this talk by Matt Kulukundis at CppCon 2017: "Designing a fast, efficient, cache-friendly hash table, step by step"

The Rust std lib HashMap is powered by the hashbrown crate which is also a port of Swiss Tables. At a brief glance Ruby/Python don’t use this approach but I don’t see any reason why they couldn’t.

I guess it took a bit longer to get it adopted within Go because of some additional challenges:
Go is much older than Swiss Tables. Since the hash table is a widely used container type and Go aspires to having a sort of "kitchen sink" stdlib I assume Go 1.0 had a hash table, and it can't be a Swiss Table because those weren't invented yet.

It's the "map" builtin. Go has a scripting-language-esque attitude of "you can build most things with arrays and hash tables". It doesn't completely preclude getting deeper but that's the general starting point.
