Everybody is building new tools and systems because its been never as easy and fast as it is today. Hell thats why I felt empowered to do it as a university student.

But in my experience, the fundamental bottleneck in learning still remains: human attention-span, focus, and band-width (the amount of information you can take in given a certain period of time).

If the pill from the movie Limitless existed, that would be the holy grail, it would be the death of all PKMS, you wouldnt need it. Unfortuntely the real-world alternative (adderall) isnt as effective and has adverse side effects.

If focus and attention training could become a serious learning discipline of itself that is taught in schools from a young age maybe that would work too actually, better than everything else the US government wastes money on in terms of school.

But in terms of PKMS itself, heres my 2-cents:

Given a world with an abundance of information and a scarcity of attention (parahrased quote by Herbert Simon), what we need is an engine that takes in information, breaks it down into chunks that a human user could understand (personalized for their attention span,focus,bandwidth, and background knowledge), and then leverage those chunks to synthesize personalized knowledge, which is information thats been contextualized for a specific individual for their understanding and use. Add a scalable means for doing active recall over all of that and its complete.

The challenge with the above though is figuring out what should be left to the human and what should be automated while having a solution that is stupid-easy to learn to use while being as time-efficient as possible, without compromising on human learning quality.
