I don't have a problem with this post, in fact I think it fully redeems any criticism by describing the stronger use cases for the language.

Takeaways:

If picking an arbitrary language to learn, if you are building small-to-medium scale things that require async, rust is not the first thing to reach for.

The stdlib and the package ecosystem is a mess.

Use if:

If you need gigascale performance and have the resources to learn it and deal with the complexity of async.

If you are writing performant global OS libraries.

If you are writing IoT and want something with more protection than C.
