AI as a learning partner, not a replacement for thinking
September 28, 2026 · 17 min read
Joe Liemandt uses AI tutors for mastery learning, Terry Sejnowski calls AI an idea pump and diagnostic partner, and Ted Gibson explains what language models do and don't understand. The best use of AI in learning is to speed practice and feedback while keeping the human work of understanding.
The rules, numbers and steps worth keeping in front of you.
- Core rule: use AI to speed practice and feedback; keep the understanding yourself.
- Terry Sejnowski: learning must be active; being told the answer does not transfer.
- Try the problem first, then use AI to check or explain your mistake.
- Joe Liemandt's sequence: worked example, initial mastery, then spaced repetition.
- Liemandt: drill basics to fluency so they stop using working memory.
- Liemandt: do not move on with an 80% grasp of fundamentals; gaps compound.
- Liemandt: motivation is 90% of learning and needs a caring adult.
- Alpha's speed claims are its own data; independent trials are still underway.
- Sejnowski: use AI as an idea pump and a second opinion, then check its ideas.
- Dermatology study: doctors plus AI reached 98 percent, versus about 90 percent alone.
- Ted Gibson: models master the form of language, not the meaning.
- Test an answer by changing a key detail of the problem.
- Sejnowski: think about a hard problem before sleep and walk without audio.
This is the short form. The full insight has every expert's reasoning, their own words and the sources.
