The first half is an introduction to Group Field Theory (GFT) and the second
half gives some exciting unpublished results exploring GFT dynamics and its relation to ordinary QFT, 4D Loop-and-Spinfoam (LQG/SF), Dynamical Triangulations, and 4D Regge gravity.

He presents GFT as a unifying framework in which several other approaches to quantum gravity fit, and which has a close relation to Feynman graphs and usual field theory.

Arguably he has an interesting candidate for the the fundamental degrees of freedom of space and matter--he discusses this in the conclusions at the end.

the talk refers to work by Oriti with a half-dozen collaborators, including several papers that are in preparation

If you are already familiar with GFT you can skip to the halfway point in the talk, where he starts talking about the new stuff.

He has the model.
50 years! to nail it down! He won't be alive and neither will I.

But for those who are new to GFT, Oriti's talk is definitely worth listening to.

GFT is a promising approach to quantum gravity that aims to unify various other approaches, such as Loop Quantum Gravity (LQG) and Spinfoam (SF), into a common framework. Oriti's talk provides a comprehensive overview of GFT and its potential applications.

One of the most interesting aspects of Oriti's talk is his exploration of GFT dynamics and its relation to ordinary quantum field theory. He presents some unpublished results that suggest a close connection between GFT and Feynman graphs, which are fundamental in traditional field theory.

Furthermore, Oriti introduces GFT as a possible candidate for the fundamental degrees of freedom of space and matter. This is a fascinating concept, and his talk provides valuable insights into this idea.

It is also worth noting that Oriti's talk is based on work with several collaborators, including some papers that are still in preparation. This highlights the active and ongoing research in this field, making GFT an exciting area for further exploration and development.

Overall, Oriti's talk is highly informative and provides a comprehensive overview of GFT and its potential applications. It is definitely worth listening to for both those who are new to GFT and those who are already familiar with the concept.
