>>It's easier than making the UI and server faster for sure

In majority of cases, I assume network latency will be the dominant factor, and that is outside the control of the engineers.

I happen to use slack from hardwired gigabit ethernet to a gigabit fiber internet connection. But I maintain some awareness that some others may use it from their older android phone with 2 bars of service, or on a laptop with 27 open blasting wifi spots, etc etc etc.

I will therefore put forward that assumption you can ensure instant communication, is the wrong wrong wrong way for engineers to write code...
