The thesis is “The future of work is agentic.” So the play is to build the ideal UI for agentic work. And I suspect, at least early on, it looks suspiciously like an IDE.

Just take everything that powers Cursor Agent and put it in a UI that doesn’t look like a code editor. Tons of possibilities here. If you’re an ambitious person looking for an idea I’d pick that ide…

Experts Perceive Differently

It’s not just that the expert thinks differently from the novice. It’s also that the expert literally perceives information differently to begin with. And the driving force behind this is long-term memory.

Comfortable Fluency in Consuming Information is Not a Proxy For Actual Learning

If you don’t practice retrieving information from memory, it dissipates quickly and almost entirely.

Long-Term Retention Requires Short-Term Forgetting

Just like successfully lifting a heavy weight forces your body to adapt to strengthen muscles, successfully recalling a fuzzy memory (lengthy wait) forces your brain to adapt to strengthen memory.

Q&A: But Don’t You Need 10,000 Hours To Learn Math?

No. Math Academy’s foundations series that goes from fractions to first-year university is benchmarked about 15,000 XP, about 250 hours of focused work. Of course, there’s plenty of university math to dig your teeth into after that, but that’s the order of magnitude of work we’re talking.

What Learning Actually Is – at a Concrete, Physical Level in the Brain

Learning is a positive change in long-term memory. By creating strategic connections between neurons, the brain can more easily, quickly, accurately, and reliably activate more intricate patterns of neurons. Wiring induces a “domino effect” by which entire patterns of neurons are automatically activated as a result of initially activating a much smaller number of neurons in the pattern.

Retrieval Practice is F*cking Obvious

In the science of learning, there is absolutely no debate: practice techniques that center around retrieving information directly from one’s brain produce superior learning outcomes compared to techniques that involve re-ingesting information from an external source.
