Erlang does not implement CSP, and if you review the very Wikipedia link you presented it should be clear. Erlang implements the Actor model, which is more flexible for distributed, fault-tolerant systems, but lacks CSP's strict formalism and synchronization semantics. The very Wikipedia article you linked to has an entire section on how CSP differs from the Actor model. Similarly Go also does not implement CSP either, although it certainly is influenced by it.

The point of my comment is that to say that Go is basically Erlang style CSP without the weird syntax is not justified as an actual quote nor as a paraphrasing or summary of anything that anyone involved in the design or promotion of Go has ever said. It's best to reserve quotes for situations where someone actually said something or as a way to summarize something for which there are ample references available.

One should not use quotes as a way to present mostly original claims that are presented as if it's some kind of already well established knowledge.
