The research paper mentioned it briefly, but I'd like to know what the major challenges were during CICERO's development and how you overcame them individually to achieve human-level performance in the game Diplomacy? 

Future generations will say that too. It's a never-ending cycle that will continue in the future, it seems. But what makes this a pivotal moment in history is that we've got a big chance in our lifetime to firsthand experience transcending exponential growth in science & technology that outshines all of history. We're damn lucky to be alive in this era.

Sometimes confusion or chaos can be interpretable, such as your strategy right here.
