I didn't attend this year's FQXi conference, but most of the talks will be uploaded sooner or later to the FQXi YouTube channel. The FQXi conferences always feature a mock debate with a role switch. I've never seen one with an actual exchange of arguments, but the debates have some amusement value. This year we have Carlo Rovelli defending String Theory ("You Loop people... insist that you cannot get any prediction from your theory. But we can't either.") and Raffael Bousso defending Loop Quantum Gravity ("What happened next was the string landscape. You've all heard of the string landscape. It's also known as 'The End of Science.'"). Enjoy.
