Though we’re doing a straight port from largely single-threaded Python, we do make some uses of Go’s concurrency features already. One engineer noted that though channels were a much-highlighted feature of Go, we’ve used the features of the sync package far more than channels. It will be interesting to see if our preferences change over time.

I keep hearing this about people using go, they aren’t using channels, it may be because it’s just not interesting to them because they don’t need the concurrency it supplies compared to other operations, or because they are wanting parallel work for efficiency and channels then add too much overhead or unsafety. This is definitely one big thing I like about Rust, Fearless Concurrency is a memeword in that ecosystem for a reason.
