Join the discord is a charmingly opaque answer to the question of where to find learning resources for an opaque topic. I'd guess OP was looking for something like youtube tutorials or short "programmer's guide to..." type resources.
Obviously an early line of research won't have anywhere near the depth, but as an example the geometric algebra community has done a great job of this. Lots of 10 minute videos to 2 hour lectures. Steve Brunton's videos are another example "learning ML math" resource that has helped me a great deal.
The thing that really boosted the GA community (I assume you mean bivector) engagement was the discord channel which was started by yours truly. You can check out the references in my paper.
Then good luck building community around Hopf algebras, you certainly know the roadmap better than I. The internet is an amazing place to spread word on better mathematical tools.
Just to let you know, scam alarms are going off in my head. You comment offering what seems to be an alternative view/opinion, and promoting your own work and research papers. When asked for more details the only thing you do is ask people to join your Discord. Although given the context, I have a hard time seeing how it would actually be a scam. Just be aware of how this appears to others.
I did not get much info at all from joining the Discord and had to learn it on my own, but the discord has some interesting info.
That said, Adam tends to follow a very precise and measurable interaction selection path with many people regarding some of his work and the discord, so I also just see it as how he interacts with others.
But yes, agreed, I wish I had a human-understandable resource that a mortal of my own kind of flesh could more easily grok. Even the 'for absolute beginner' online tutorials are a swamp of symbology and prior assumptions, and it doesn't even seem to be that terribly difficult of a concept on the whole, at least for the basics of it.
Just my 2c, lots of good and mixed for us all in this crazy road we call life! <3 :D :)))) :D
