There are a lot of product design reasons that I could argue encourage more synchronous communication in Slack than in email, but the real proof is in the outcomes. Have you actually been in organizations where the latency expectations for reading and responding to email are equal to or shorter than for Slack? In my experience email correspondence is _much_ slower and long-winded, because people are almost never exchanging them minute by minute and waiting in real time on the thread for the next update.
