Messages are not really real time either--a phone call or FaceTime would be on the other hand. Sure, a lot of people use them in a faster than email fashion, but it doesn't really change the overall use and hierarchy of what's included and how it works. So, while it's not an exact comparison of course, I would say it's a very valid one as far as the similarities in flow go.Not a good comparison at all, two completely different apps. Messages is used in real time whereas mail is a much slower response time.
That said, this probably isn't the best thread for this part of the conversation as it's not really about autocorrect (and seems like this subject is being discussed in another somewhat more appropriate thread already too).
