Important to remember when looking at things like this: check the dates and compare to alternatives.
Lattice QCD may account for many things brought up in this lecture so it may help in comparing Lattice QCD to Nima Arkani-Hamed’s ideas and see what’s now accounted for since 2014 vs what’s not.
I bring it up because I’ve had my favorite horses that I cheered on in the race only to find them leaving the racetrack upon better if not as beautiful theories came along, particularly testables.
There was one that I adored that put mass into a parallel dimension that was only slightly removed. Mathematically it worked out great and I loved the notion. But as far as I know it didn’t last. Beautiful theories do need to be compared against what can be checked. That doesn’t take away from their power of course.
