Channels are for passing a message with a single owner, a producer and a consumer. There are single-producer, multi-consumer channels but it's when any consumer can handle the message, not all consumers must handle the message, for example a task/job system where any CPU can handle the task. What you seem to be looking for is a pubsub / publish-subscribe system or an event bus. > Also, if using spawn, what's the alternative to channels? Channels are for `spawn` situations.
