Go and Java/C# (if you forgo all the OOP nonsense) aren't much harder to write than Python, and you get far better performance. Not all the way to Rust level, bur close enough for most things with far less complexity.
Python just has too strong network effects. In the early days it was between python and lua (anyone remember torchlua?). GoLang was very much still getting traction and in development.
Theres also the strong association of golang to google, c# to microsoft, and java to oracle...
Go is criminally underrated in my opinion. It ticks so many boxes I'm surprised it hasn't seen more adoption.
Rust really ticks the "it got all the design choices right" boxes, but fighting the borrow checker and understand smart pointers, lifetimes, and dispatch can be a serious cognitive handicap for me.
Go and Rust try to solve very different problems. Rust takes on a lot of complexity to provide memory safety without a garbage collector, which is fine, but also unnecessary for a lot of problems.
