As a beginner, these are questions that lead to a big rabbit hole for me. 1. Yes, it seems Projective Geometric Algebra is new enough that the terminology and symbols are still being debated. 2. Yes, people who "get" it seem pretty convinced. I think the newish PGA is attractive for convincing real-time graphics software engineers and hardware engineers. For example, it has 16 floats in R(3,0,1) too. 3. The community is there to help spread the knowledge and to help as you start finding out about all the other Geometric Algebras. And overcoming the Euclidean mindset is tough. This is the first bit of higher-than-Calc math I've worked at in a long while and it feels like it's bending my mind in a good way, like Lisp did.
