I think the author proposes geometric algebra for widespread use in teaching fundamental physics. That's a good idea, it unifies a lot of things and brings new insights! Hestens seems to be quite popular with his opinion, see for instance https://link.springer.com/chapter/10.1007/978-94-011-5036-1_24 https://link.springer.com/chapter/10.1007/978-94-011-5036-1_... and https://en.wikipedia.org/wiki/Geometric_algebra https://en.wikipedia.org/wiki/Geometric_algebra Very interesting! But it requires really a skilled lecturer to make students understand the concepts. I've heard advanced mathematical physics by a, well, bad lecturer, who taught everything on some abstract level which I never heard from previously (and after). I had to learn differential geometry and all that later on my own in order to graduate in some topic in general relativity.
