Has there been any progress in the last 10 years since the discovery of amplituhedron?

I'm not the best person to answer this, but my understanding is yes. The claim is that it's an almost ubiquitous phenomenon; many theories, I think even including non-supersymmetric theories, have something similar going on where a geometric object can determine the results of certain Feynman diagram calculations (maybe still only at tree level). There was even an example I saw in a lecture where some topics that would be taught in a first year quantum field theory course fit into this framework.

Nima Arkani-Hamed has a bunch of lectures on YouTube that are pretty entertaining, and while they can get quite technical, he says a lot that can be appreciated without understanding the details.

Thanks! I saw a couple of his lectures on YouTube, and it's very difficult to understand, whether it is just marketing, or there is some progress going on in the topic
