I think the language is doing great, not least _because_ it has slowed down a bit. To me it's an indication that is has found a decent plateau right now where people can get useful things done, and where the Rust language and compiler teams are eager to provide a stable product that doesn't break things willy-nilly.

A lot of the complaints I see are not super well thought through. For example, a lot of people complain about async being too explicit (having a different "color" than non-async functions), but don't consider what the ramifications of having implicit await points actually are.

Even in this otherwise fine article, some of those desired Fn traits are not decidable (halting problem). There's a bit of a need to manage expectations.

There are definitely legitimate things to be desired from the language. I would love a `Move` trait, for example, which would ostensibly be much easier to deal with than the `Pin` API. I would love specialization to land in some form or another. I would love Macros 2.0 to land, although I don't think the proc-macro situation is as bad as the author presents it.

The current big thing that is happening in the compiler is the new trait solver[0], which should solve multiple problems with the current solver, both cases where it is too conservative, and cases where it contains soundness bugs (though very difficult to accidentally trigger). This has been multiple years in the making, and as I understand it, has taken up a lot of the team's bandwidth.

I personally like to follow the progress and status of the compiler on https://releases.rs/. There's a lot of good stuff that happens each release, still.
