I write Go daily, and I don't think CSP really panned out. For most applications, I find it's much easier to use a mutex and standard threading tooling than channels/CSP. That might be an artifact of how channels are implemented and their many hidden error cases--perhaps a better channel implementation could change the calculus. There are lots of reasons to prefer Go to Rust IMO, but I don't think CSP is among them.

It's easier to write code with standard threading tooling but I think CSP is much, much easier to debug and avoid deadlocks.

This has (still to my surprise) not borne out in real-world cases, at least to the extent Go channels "do CSP".

That has not been my experience with CSP via Go channels after 8 years of solid use (I still use channels here and there, but not in a CSP pattern). Different strokes, I suppose.
If anything, I find Rust returns flexibility to me in programming choice that Go made me forget I had. There are places where library support in Go is still richer, but language support has been stellar across the board in Rust.
