Async rust might suck, compared to async in higher level languages, but for someone comming from C, async rust simplifies a lot of stuff. It often feels like a lot of criticisms of rust boils down to the fact that rist was sold to both people using low and high level languages. I don't doubt that async rust is shit when all you want is a faster typescript.

Edit: I certainly also have my criticisms of rust and its async implementation, and I think some of the authors concerns are valid, it was just an observation about the tension between the needs of the two groups of users.
