On: Go Concurrency Distilled

Yup. That’s because cancellation isn’t native, but part of the context object and requires cooperation. In a language where goroutine switching is preemptive rather than cooperative, I find it odd to have cooperative cancellation, until I realize that Go doesn’t have exceptions and probably will never have them.

exactly - once you accept go has no exceptions, context cancellation is basically the least bad way to tell a goroutine to stop.
