Teaching AI
One idea, followed from rules written on a page to systems nobody fully controls. Thirteen modules for high school teachers — the concepts first, then how they get taught.
The arc, in six moves
Every concept in the course, in the order it has to be learned. Each phase only makes sense once the one above it is in place — which is also why the modules can't be reordered casually. The last two are different in kind: one asks whether today's approach is enough, the other asks what follows if it is.
What the machine is
Modules 1–2Four words that get used interchangeably and shouldn't be, and the seventy-year shift in who supplies the rules.
How it predicts
Modules 3–4Underneath text, images, audio and video is one operation repeated: guess what comes next. Then make it enormous.
How it got capable
Modules 5–7The phase most explanations skip entirely. Prediction alone makes a text continuer. Everything that turns it into an assistant, a reasoner, or a coder happens here.
How it acts
Modules 8–9Nothing new is added to the mind. It gets hands, and stops being watched at every step.
Are new model types needed?
Modules 10–11An empirical question the field has not settled: does more of the current approach get you there, or is something architecturally different required? This is where students should be arguing rather than absorbing.
AGI and ASI
Modules 12–13What follows if the answer above is yes. Forecasting and consequences rather than architecture — and the place where definitions do the most work, because almost every disagreement here turns out to be about terms.
Thirteen modules
The arc above, broken into teachable units. One question asked at rising stakes: what is the machine actually doing, and what does it mean that nobody wrote it down?
What AI Is
Rules, examples, depth, generation — and the control-for-capability trade. Deliberately leaves "does it understand" unsettled.
What generative AI does
One mechanism, four media. Text, images, audio and video are the same trick.
Next-token prediction
Tokens, context, sampling, and why fabrication follows structurally. Carries the expiry note on "it just predicts the next word."
Scale and data
Scaling laws, what's in the corpus, dataset bias, and the data wall.
Post-training and RLHF
Autocomplete to assistant. Preference data, reward models, reward hacking, and where humans leave the loop.
Reasoning and test-time compute
Thinking before answering, why math and code jumped first, and the faithfulness problem.
Better data, round two
Synthetic data, training environments, and actively sourced data. DoorDash Tasks is the case study.
Agents
Tools, memory, loops, computer use — and why autonomy compounds error.
When agents go wrong
Prompt injection, scope failure, and the supervision dilemma. Nothing malfunctioned.
World models and robots
Does predicting video amount to understanding physics? Opens the question of whether a new kind of model is needed.
Can language represent the world?
The grounding debate. Built as a debate, not an explainer — two evidence packets, a round-runner, and a take-home that replaces a test.
AGI
Four competing definitions, four forecaster types, and five questions for reading any timeline claim. No specific forecasts, deliberately.
Superintelligence
Recursive improvement, the control problem, and the full range of serious positions. Includes a note on handling student anxiety.
