I think a lot of the materials that the Go folks put out in the early days encourage a very channel-heavy style of programming that leads to extremely bad places.
Nowadays the culture seems to have evolved a bit. I now go into high alert mode if I see a channel cross a function boundary or a goroutine that wasn't created via errgroup or similar.
People also seem to have chilled out about the "share by communicating" thing. It's usually better to just use a mutex and I think people recognise that now.
This is true. I have been writing Go for years and still think channel is a bit too low level. It probably would've benefited from a different layer of abstraction.
