I mean in certain contexts absolutely. I certainly wouldn't use smart compose to write a novel, but then I don't think it would be very helpful for creative writing where or writing where my focus is on tone.
But for otherwise mechanical things ("hey can we set up a meeting tomorrow", "do you want to grab lunch at ____ today"), the form is mostly irrelevant. It's the kind of thing where if we weren't in a formal context, I'd write as "hey u wanna grab fud at ____ later". I'm not losing anything by having a tool formalize that to "Hey do you want to eat lunch at ____ today." Again, we already do that a lot. As far as I can tell, this is just doing that a bit faster.
I think this is a dangerously stupid way to think about linguistics.
