alt Hacker NewsYes but my point is that their argument is undermined by the extreme clumsiness of standard mathematical physics notation. I don't believe GA is the best possible notation for physics but it could be a stepping stone. We need more people who explore such things rather than more people who call each other crackpots.
Author is not calling them crackpots, and _is_ strongly advocating for some of their new notation, and explicitly encouraging readers to find better notation where he dnsagrees with theirs.
