History and analogy

There's a lot to talk about. But in this post I just want to mention two perspectives. 

The first is Geometric Unity's place in the spectrum of approaches to quantum gravity. I propose a fourfold way of thinking about it: that Geometric Unity is to Loop Quantum Gravity, as string theory is to general relativity. I like this as a way of thinking about the options in gravitational theory: metric-based versus connection-based approaches to relativistic gravity and the theory of everything. 

The second is to think of Weinstein versus Witten as similar to Schopenhauer versus Hegel. Hegel was the best-known philosopher in Europe, Schopenhauer was a young unknown, yet he dared to schedule his lectures for the same timeslot as Hegel. No-one came and he left academia, and it took thirty years for him to be noticed again; but in the end his work made its mark, not least by helping to create Nietzsche.
