Pedagogy at scale
Close Bloom's 2-sigma gap, every child deserves a personal tutor, and AI may finally make it tractable.
The scale of it
share of 10-year-olds in low/middle-income countries who cannot read a simple text
The capital on it
Edtech venture funding worldwide. Excludes public education budgets (~$5T/yr, overwhelmingly status-quo delivery). Post-2021 crash: the boom peaked at ~$21B and innovation capital has fled.

The prize at the limit
A company that delivers a genuine tutor-quality education to anyone, in any language, for near-zero marginal cost becomes the default layer for human capital formation worldwide — the closest thing to compounding the entire species.
comparable: the "Google of learning" — a new education default · confidence low · a ceiling, not a forecast
The trade: demand is high, only $3B/yr of capital is flowing (0.02× its fair share), and the prize at the limit is $300B. This is a Request for Startups and a Request for Investors at once.
The summary lives here. The full whitepaper walks through the four-axis ranking, existing alternatives, proposed direction, cost & scale, and suggested investors — in the spirit of Hyperloop Alpha.

Neglectedness
5/10Education spend is huge, but the high-leverage wedge (scalable 1:1-quality tutoring) is barely funded relative to its potential.
medTractability
7/10Bloom proved 1:1 tutoring lifts outcomes two standard deviations; LLM tutors can now approximate it at near-zero marginal cost.

Three-lens scoring
Benjamin Bloom's 1984 research showed one-on-one tutoring raises student performance by 2 standard deviations versus classroom instruction. The problem was cost: one tutor per child is infeasible at population scale. AI tutoring changes the economics. 1.5B children are undereducated globally (UNESCO); billions more adults lack skills they could have acquired with better pedagogy. This is the problem Deutsch writes about most directly in The Beginning of Infinity, better explanations compound across generations.
The success vision · 10 years horizon
If we solve this, here is the world we get.
Before · today
1:1 human tutoring produces +2σ outcomes vs classroom (Bloom 1984) but is unaffordable for most. Median schooling under-delivers; global learning poverty ~70% in low-income countries.
After · 10 years
Every learner has access to AI tutoring matching the best human tutors, in any language, at near-zero cost. Bloom 2-sigma becomes the default, not the exception.
Voices on this quest
4 thinkersBad explanations waste billions of childhood hours. Good explanations compound across generations. Pedagogy is an epistemology problem.
The Beginning of Infinity, chapter on bad philosophy
Asks whether we can dramatically improve the quality and speed of learning. Cites tutoring and personalized instruction as high-leverage unsolved problems.
Education quality is the compounding lever. Progress requires transmitting knowledge at higher fidelity and lower cost to each successive generation.
Finding and developing talent is an underrated problem. Most selection is bad, most mentorship is worse, and the tails of ability are where civilizational value compounds.
