I dislike some of this article, my impression is similar to some of the complaints of others here.
However, are Go programs not supposed to typically avoid sharing mutable data across goroutines in the first place? If only immutable messages are shared between goroutines, it should be way easier to avoid many of these issues. That is of course not always viable, for instance due to performance concerns, but in theory can be done a lot of the time.
I have heard others call for making it easier to track mutability and immutability in Go, similar to what the author writes here.
As for closures having explicit capture lists like in C++, I have heard some Rust developers saying they would also have liked that in Rust. It is more verbose, but can be handy.
