Hard disagree on this. Large production apps that use channels have very subtle bugs that cause all kinds of annoying issues that only come up under load in prod. I have been using go for ten years and still pick it as my language of choice for most projects however I stay away from channels and especially any complex use of them unless it’s 100% required to scale the application. Even then you can most of the time come up with a better solution by re architecting that part of the application. For pet projects go crazy with them though.
