Got nothing to base this on but intuition, and inspired thought.
What my mind just saw was that AI will be playing a dominate part in this debate. It's like Trump is not going to be debating with a human at all, but with a DebateBot that has been specifically designed to debate Trump and win.
This bot will not appear as super intelligence, that would be a giveaway, but responses from Biden, and pushback from moderators will be AI driven such that the perfect counter is put forward, but with the flaws and patterns that make everything sound legit.
Yet, The spaghetti is on the wall from Biden's brain blow out. They didn't need AI to get Biden elected. This might actually help him seem slightly more normal.
