That's only for single message info-dumps or single query-response. If I need to tell you something, it will save your time if I distill it. But note that it may be more efficient overall to do it by voice, or maybe my time actually is more valuable than your time. (or vice versa).
If we're doing it interactively, I can verify your comprehension and limit my need to elaborate, saving us both time.
And if we need back-and-forth collaboration, interactive is likely to be much better than multiple interruptions and context switches.
My general rule is, if it's going to be more than 2 back-and-forth exchanges, do a voice call.
And waiting while someone types a response is pure waste.
