I have playing around with this in my heads for the fun of it. I have survived most of my life without a dual and could probably go much more if I need to. Most people don't end up marrying their dual either.
As much as I do favor duality, I think a sobering or alternate look at it can be helpful.
I want to take on a different perspective for the hell of it. Do we NEED duality? Is duality always the best? Are there drawbacks to duality that nobody talks about?
