The discord/slack as a means of communicating technical questions is a great example how an entire generation refused to accept a solid solution because it didn't fit their impediment desire. (Need is wavy here because the responsiveness isn't the original need.. it's the answering of the question that's a need.. being instanteous is just a convenience )
What am I saying: We've had technical mediums to discuss technical problems asyncly for a while now. (Usenet, reddit, phpbb, hackernews) Instead lots of younger people in the industry decided they weren't obligated to use those and foolishly decided to move to a more transient form of communication for everything.
In doing so we're losing technical knowledge, misinformation is spreading, and we're running into development of technology that has a limited set of experience behind it.
What I suggest: Figure out how to enhance async communication to switch to syncronous and store the results of that. (in other words identify deficiencies and try to solve the problems there rather than completely scrapping them)
