The thing is, most discussions about Go are about adding features Rust has or making changes where Rust has something relevant to say.

I chose my analogy carefully. Coca-Cola tried to change its recipe to make it sweeter because they did studies and found people liked the taste of Pepsi more. So any discussion of changing Coke's flavor means Pepsi is highly relevant. But the converse is not necessarily true. Pepsi doesn't have any (recent) history of trying to match their flavor to Coke.

Maybe a better analogy is this: if Mercedes comes out with an electric car, you should expect to see Tesla in the discussions. But if Tesla comes out with a combustion engine, there's nothing particularly relevant about Mercedes in that discussion.

I'm sure that if there were discussions about adding structural typing or lightweight fibers to Rust, then Go would show up. But most of the discussions tend to be around adding generics or sum types to Go.
