I really like Go, but I mostly agree with this assessment.
Perhaps the one place where Go has a slight edge on Rust is portability. Go binaries (especially those compiled without cgo) are even easier to distribute- you don't need to worry about openssl, for example. And let us not speak of distributing python here...
On the other hand, if your application does not need Python's extensive ecosystem or Rust's comprehensive typing system, Go is a highly productive language that gets out of the way and lets you get stuff done.
