I have posted the following comment to a YT video (*),
but they are not allowing it to be visible, so I'll
try to post it here, it is indeed a question (answering
which I think presupposes that one has an idea of what
"Geometric Algebra" (**) in fact offers):
<< @34:12 - Isn't "Geometric Algebra" (at least potentially,
if it turns out to [fully] work), with everything including
gravity done in flat space-time, a solution to that problem
of **a description of matter and matter fields that is
independent of geometry/metrics**? >> (emphasis added)
Any feedback/insight very welcome, thank you.
