Curt Jaimungal made a deep dive into Eric Weinstein's theory of Geometric Unity. He published a video which he calls the Iceberg of Geometric Unity and a comprehensive and technical addition. It took 250 hours to produce ~3h explanation, and it will presumably take much longer than three hours to understand the different pieces of mathematics (excerpt of interesting topics with links below) just as preliminary, let alone the assembly into a theory of the universe.
Why we should stop saying "explain it to me like a five year old" peregrination
There is a lot of mathematical background which might be helpful to understand the video.
At timestamp ~3m50s it is visible that this list is by far incomplete.
