My point is that “sophisticated abstractions” should reduce complexity, not increase it.

If Tokio’s abstractions are seemingly increasing complexity, maybe they aren’t sophisticated abstractions.

This is a criticism of the OP, not Tokio.

I understood your point. As my comment alluded to, the criticisms of tokio this blog post is attempting to address have to do with the implementation complexity - abstractions do not reduce the implementation complexity of themselves.
