I’m open to the idea and I probably haven’t thought about it as much as you, but I’m skeptical about the way you discuss going about it in your post and also that the work of the experts that seem to have inspired you is impactful.
I suspect the techniques you’ve discussed will greatly improve your memory, but I’d guess that it’s often not worth the time to memorize something. Based on my experience working as a software engineer, my attitude has been you can’t learn everything . At least in software engineering, you need to adapt to new languages and frameworks frequently and I’d imagine other relatively new fields are similar. In software engineering (and maybe these other fields) the most (if not the only) important thing to remember is what you need to google.
Additionally, I’d also guess that a lot of the truly most impactful work comes from learning about new domains . This also can’t be learned through memorization. Even googling the right questions often won’t give you a quick answer. Haseeb Qureshi wrote a post about this type of learning, which he calls “unstructured learning” that I think is worth reading https://haseebq.com/the-hard-thing-about-learning-hard-things/
I’m aware that you said you mentioned you’re not targeting superstars, but as far as I know there’s no reason superstars would learn differently than anyone else. I’d also guess anyone can get a lot more out of themselves if they do their best.
I’d also guess that it would be hard to make your idea be much more than an incremental improvement over the Learning How To Learn course. I admittedly haven’t taken that course so take that with a big grain of salt.
Maybe it could be worthwhile to try to create a course or program that focuses on teaching unstructured learning. I don’t know how you’d go about it and I think there’s a high chance the course would be crap, but maybe its worth the risk?
If I define impact as change and outcome as a result, then isn’t every occurrence of an impact an outcome? Are you defining those words differently?
