I forgot to post this excellent layman's article in Quanta Magazine from last year, describing just how far Nima and friends have come in discovering a simple and primitive mathematical structure from which shared Experience emerges...

" In the fall of 2022, a Princeton University graduate student named Carolina Figueiredo stumbled onto a massive coincidence. She calculated that collisions involving three different types of subatomic particles would all produce the same wreckage. It was like laying a grid over maps of London, Tokyo and New York and seeing that all three cities had train stations at the same coordinates.
“They are very different [particle] theories. There’s no reason for them to be connected,” Figueiredo said.
The coincidence soon revealed itself to be a conspiracy: The theories describing the three types of particles were, when viewed from the right perspective, essentially one. The conspiracy, Figueiredo and her colleagues realized, stems from the existence of a hidden structure, one that could potentially simplify the complex business of understanding what’s going on at the base level of reality.
For nearly two decades, Figueiredo’s doctoral advisor, Nima Arkani-Hamed, has been leading a hunt for a new way of doing physics. Many physicists believe they’ve reached the end of the road when it comes to conceptualizing reality in terms of quantum events that play out in space and time. Such language can’t easily describe the beginning of the universe, for instance, when the space-time fabric likely didn’t exist in its current form. Arkani-Hamed therefore suspects that the usual notion of quantum particles moving and interacting in space-time is an approximation of deeper, more abstract concepts, which, if found, could serve as a better language for talking about quantum gravity and the origin of the universe.
A major development came in 2013, when Arkani-Hamed and his student at the time, Jaroslav Trnka, discovered a jewel-like geometric object that forecasts the outcome of certain particle interactions. They called the object the “amplituhedron.” However, the object didn’t apply to the particles of the real world. So Arkani-Hamed and his colleagues sought more such objects that would.
Now Figueiredo’s conspiracy is another manifestation of abstract geometric structure that seems to underlie particle physics... "

We shall not cease from exploration
And the end of all our exploring
Will be to arrive where we started
And know the place for the first time.
