And they made dozens of hour long videos about that? That's insane. And the arrogance of calling it "geometric algebra" mile they invented a new field of math?!

One could argue it is more about physics than math. GA has simpler expressions for a lot of physical topics.

Perhaps, but it's not new math (Clifford algebras are almost 200 years old). Shrouding it in a veil of buzzwords and pizzaz makes you look more like con artists than scientists. A sentence like this one is just absurd:

> Clifford's Geometric Algebra enables a unified, intuitive and fresh perspective on vector spaces, giving elements of arbitrary dimensionality a natural home.
