MCTS always in non-zero signal regime
AlphaGo's elegance is that MCTS always produces a training signal — the policy is never stuck at zero pass rate waiting to stumble on a win.

RL is even more information inefficient than you thought
At 2:14:18 · chapter starts 2:08:56
Dwarkesh presents an information-theoretic argument: naive RL learns near-zero bits per sample at low pass rates, while supervised learning learns negative log(pass rate) bits. The gap is enormous. [1] — Dwarkesh Patel "With a 1-in-100K pass rate, supervised learning gives you negative log(1/100K) = ~17 bits per sample. Naive RL gives you essentially zero. …" 2:09:35
RL Is Even More Inefficient Than You Think
With a 1-in-100K pass rate, supervised learning gives you negative log(1/100K) = ~17 bits per sample. Naive RL gives you essentially zero. You spend almost all of early training in a regime where nothing is learned.
RL bits per sample vs. SL
Naive RL learns at the rate of the entropy of a binary random variable per sample, while supervised learning learns negative log(pass rate) bits — orders of magnitude more at low pass rates.
What Automated AI Research Can and Can't Do Yet
LLMs can autonomously run experiments, tune hyperparameters, and optimize code. What they can't do: decide which question to investigate next, or recognize when an entire research track is a dead end and pivot to something fundamentally different.

Ad-based monetization works well for game apps where users spend extended time in-session, as seen with Grid and Wordle.
Ads don't work for tool apps
Tool-focused apps like PuffCount are poor candidates for ad monetization because users don't stay in-session long enough.
Hard paywall is unskippable
A hard paywall is a screen that blocks all app features unless the user pays or starts a free trial — it cannot be dismissed.
Two core monetization models
Mobile apps are primarily monetized through either ads (best for games) or in-app purchases/subscriptions (best for tools).
