An often repeated point on this forum: A lot of our comms are text. You don't want stall and lose attention to comms. Makes sense to train and have the flow on auto.

I've never had an issue where communication with my team has been hindered due to my typing speed not being high enough. If anything, I've been in plenty of text-based communications where it might have been beneficial for everyone to slow down a bit in how quickly they were sending messages in favor of more thoughtfully reading through everything before responding.
