I don't have a use for Rust on my daily work, and would rather see Java finally adopt the features it missed down from Oberon and Modula-3 for systems programming, however we will have to disagree on the "mediocre" adoption.

So many language designers would dream to have such adoption numbers by tech giants for their hobby language.

Of course Rust is very popular compared to any hobby language (and many non-hobby languages), but that is not the goal it set for itself to be judged by.

Correct, the goal is to be foster the adoption of safe systems programming, which given the uptake across all major cloud hyperscalers powering the Internet, and all major OS vendors selling hardware (with exception of one because they have their own alternative), is what I would consider a large success of anyone dreaming to get their language adopted at scale.

All major cloud vendors deploying my Java, .NET and nodejs containers do so, in infrastructure that has various layers of Rust code in it.

To value that as mediocre is quite strange.
