I didn't mean technical overhead, I meant presentational overhead. Email was fine, nay, great, for people to have extended group discussions in, so long as everyone was willing to follow some rules. Then Outlook plus the Eternal September came along and now everyone is reinventing quoting repeatedly (and poorly). Branching is a whole thing (or mostly, not a thing when it needs to be a thing). And we don't even need to discuss what happens to HTML in emails. Chat allows for fast questions, fast responses. This makes it harder to have lengthy or broader discussions in. Neither of those, however, says that chat has to ephemeral while email is lasting, which was the point I was responding to. If you want chat+history, you can't swap out chat with email and say "there, now you can have a history" - you just changed a LOT of things.
