I've watched a few talks and seen cool computational demos about it (see for example https://news.ycombinator.com/item?id=22282452 ), but I still don't really understand it... or should I say I can't "wedge" it into my head ;)

The uniformity of operations and the fact it works in all dimensions is very appealing, but I remember there were some very counter-intuitive aspects too, so I'm not fully on board. Still very cool though!

I guess old school vectors, dot-, and cross- products have the benefit of history behind them, so they feel more intuitive, whereas geometric algebra operations feel somehow foreign to us (to me at least). It would be interesting to see what happens if a student learns geometric algebra first, maybe it will feel more natural then.

Thanks for your take on it!

Yeah, I've noticed some people [0] advocating for using it for all physics as soon as possible too.
