So coincidently, Go and Flutter is in this. But it might be a good point as Google has a great financial capability to keep these languages going forever.

Agreed, examples of other languages compiled to machine code are C (Microsoft), C++ (EA Games, VMWare), Erlang (WhatsApp), Haskell (Facebook, IBM), and Rust (Dropbox, Discord). No doubt, all of them are great languages.

An above-average speed will do, as long as it provides value to the end-user.
