I didn't come here for an argument

 I was listening to Julius Kuschke's Narrascope 2019 talk about interactive dialogue systems, and it occurred to me that we don't see enough dialogue systems where you get at least one of the options almost as soon as the other person starts talking. Because, let's face it, people do not listen very well. Sometimes they're just waiting until the other person stops talking so they can say what they planned to say all along, and some don't wait. 

Firewatch gives you dialogue options before your dispatcher is done talking. But the conversations are fairly slow and thoughtful. It's not really the cut and slash of repartee.

Obviously, this sort of system requires a bit more programming (gasp!) and the conversations have to be designed more carefully. But it does eliminate those dreadful pauses that kill the momentum in most conversations with NPCs. 

I'd love to see a dialogue system where individual responses pop onscreen as the NPC's dialogue triggers them, so your "yeah yeah yeah whatever here's what I want" response might pop up immediately, while an emotional response to the NPC's heartbreaking dilemma might require listening to their whole speech. 

What would be superfun would be the occasional dialogue option that the NPC interrupts, but that's probably too much to ask.
