Indeed, I included it to show that even though everyone might seem like they're clamoring for deep work products, the reality is that sometimes people just don't care enough. Level's founder Derrick Reimer had a hypothesis that people hated Slack (and particularly its interrupting notifications) that he wanted to make a product that was async. Turns out people don't actually care enough to change their entire communications workflow.

I think the bigger problem there is missing who the real customer is. Slacks pay-for features are targeted not at the users but at management, and management gets to dictate tools more often than not. Individual developers would absolutely jump on an async platform, but they're not the decision maker.
