You cannot speed run human learning. Investing time to read and absorb the material, repeatedly exercising and expanding your understanding, is the only path.
Not coincidentally, this is exactly how we train our AI.
Edit: but to answer your question, an AI harness can only emulate the best teaching methods. Learning is up to the human.
I really disagree with that stance. It would be trivial to have it ask you questions about what it produced to ensure you understand. I’ve literally already done that several times.
"Understanding" someone else's solution is not comparable to solving it on your own, even if you can answer some questions about it. It builds extremely fragile surface-level understanding.
That struggle and repeated failure before finally connecting the dots on your own is how you build intuition and deep understanding.
Yes, all learning takes practice, it's the core of how our brain learns things. Any tool that eliminates the practice part means suboptimal, or zero, learning. Practice isn't just for physical tasks like riding a bike. All skills take practice, meaning repeated cycles of failures over a long time horizon.
And if they can do that- could they do it to themselves- going from a junior to a pro conversation?
