“This is a great question. I've thought about it a lot, and I'm sure if you ask me five or ten years ago, the answer would be different. We've now done multiple things together and had great success. I don't think either one of us would work on something without the other. I try to frame it like this. What did Siamak teach me that I would not have been able to learn on my own? Because I think that answers the question of what's complementary and where are the gaps.”
