I think this is what a lot of people who complain about Slack don't get. It's just a better message queue for your business. The fact that you can funnel all your business events, regardless of whether they originate from humans or bots, into one place and then each worker (again, either human or bot) can subscribe/filter/react to relevant events is super powerful. However, if you try to use it as a corporate SMS platform or email replacement, you will very quickly feel overwhelmed because both of those message queues are designed for much lower throughput.
