What do you mean, forget? The whole point of the OP was that they are aware of how much time learning takes in real life, otherwise it wouldn't be a problem to solve.

Not op.

the op probably means that learning kung-fu takes _a lot of practice_. In the real world probably years not just a summer camp :-p

No, but a philosophical argument that showed how it was impossible would be almost as useful. You can just give someone a magic feather and let them believe they have become something, which is sufficient for many purposes.

Remember that in the Matrix story, a world in which they could download skills from the simulation and instantly become things by essentially just imagining them, so long as they stayed within its confines - was the world they were trying to escape. If you tell a 5yr old that their crayon drawing is beautiful, they become an artist, and for most people, that pattern doesn't change for the rest of their lives unless they become disillusioned and pursue their destiny as an existential hero.

Maybe there could be some neural interface that lets you transmit and replay brain activity through other bodies faster than language does now, or muscular electrostimulation that simulates say, deadlifting, but just as having a music collection doesn't make you a musician, I'm with Feynman in that I don't think we understand what we don't ourselves create.

I know it's not exactly what you asked for, but in my experience, spaced repetition is borderline science fiction -- if implemented properly. It's not as instantaneous or cool as The Matrix , but it does feel like magic when you can remember obscure words or concepts years after entering them into a SRS program.

Is it really that good?

Yes. I have concepts in Anki that I will be promoted to repeat again in 4 years and I've had to repeat 4-5 times in the past two years.

Knowing how to do something doesn’t live outside the brain.

You can erase entire categories of knowledge by damaging the brain in particular areas. There is no reason to believe the opposite is not true.

Therefore it is a matter of modifying the state of the brain to learn or know something.

Not a neurologist, but my hunch is that even if we had perfectly working brain implants, this would be impossible the way they do in the movie - or at least would require lifelong monitoring of your brain structure before it could be done (which, arguably, would be feasible for people spending their life in a tub like in the movies - but infeasible for us)

As a start, what "data format" would that downloadable knowledge be represented in? It would have to be interpretable by your brain and able to reference knowledge and other concepts you already know about - not just explicit knowledge, but also motor memories, etc. Unfortunately, all this stuff depends heavily on the experiences and learnings you personally have made until this point - so this is probably completely unique for every brain.

Many Japanese comics, stories, etc. showcase and celebrate the hero's trip from 0 to 1 on a scale of 100. I believe this is an Asian cultural thing, were struggle _matters_ and even little steps - sometimes invisible to others - are celebrated. Most US based comics, movies, books, short-stories celebrate the hero's accomplishment _after_ the training period. The hero is already the _the best one around_ in whatever a…

Does he? It’s been a while since I’ve read the books but my recollection is that he never actually develops a ton of deep skill, or at least it’s never seen. His biggest accomplishment in magical terms seems to be his ability to do the patronus charm at an earlier age than most. Otherwise most of his success comes from 1) bravery, 2) friends, or 3) luck. At the end he chooses to be an auror, which I thought was odd because it seems like he’s poorly equipped to do that job.

It’s true that the books do not paint his journey as instantaneous (except his proficiency flying the broom). But they also don’t really paint his journey as ending in a place of impressive skill.

What SRS software do you recommend?

Anki

OpenSource and Libre!

I'm not a neurologist too but what if you can do it without brain implants? Something like transmitting data in the form of waves to brain.
