C doesn’t have methods, interfaces, closures, newtypes, packages, map or safe slice and string types, or safe automatic allocations.

What bad faith nonsense.

And before generics it could not even implement maps in the language itself, hence my comment.

I do not think this is true. Async programming via channels in Go is a big win and way more expressive than what any C library can give you. Also, higher order functions and interfaces are good. On top of that they added generics. I think that it is more than enough of a practical language already.
