AI Fundamentals & Mental Models

The playbook

Nate's core move across this cluster is teaching one idea from a dozen angles: everything an AI touches gets broken into tokens, embedded into a shared vector space, and processed by attention — and once you see data that way (text, code, images, audio, protein sequences, even action trajectories), you start seeing where AI can and can't actually help. The A-to-Z literacy guide, the Notebook-LM explainer series, and the "Indiana Jones" tokenization piece all teach this same core model at different depths, because for Nate literacy is a moving target — what counted as advanced in 2023 (knowing what a token is) is table stakes by 2025.

The second axis he keeps returning to is scaling. Model-size scaling gave way to a second law — inference-time/reasoning compute (o1 to o3, Claude's hybrid "extended thinking") — by early 2025, and Nate initially treated reasoning models with near-unqualified enthusiasm ("The New Laws of Intelligence," written days after o3, floats 13 spicy predictions including that ethics itself gets easier as models reason better). By mid-2025 his position visibly cooled: "Scaling Isn't Destiny" and the Apple "reasoning cliff" piece argue that context brittleness, short-horizon memory, and messy real-world data are separate research problems scaling doesn't touch, and that production systems need an explicit escalation architecture — knowing when a model is out of its depth and handing off, rather than trusting a confident-sounding chain-of-thought. By late 2025 and into 2026 the framing shifts again toward measured optimism: METR's time-horizon data shows real, compounding capability growth (the "super-exponential"), but the gap between 50% and 80% reliability is where the actual work lives, and no consumer product has yet cleared the "anticipation" bar (acting before being asked).

The throughline for what stays human: taste (recognizing when technically-correct output is contextually wrong), judgment (knowing what's actually worth solving), and specification/verification skill (defining tasks precisely enough to delegate, then catching failures that look like successes). Nate increasingly frames this as a structural division rather than a competition — AI wins wherever a task needs more held context or perfectly consistent rule-application than a human can sustain; humans win wherever it needs novel judgment, business trade-offs, or knowing which failures actually matter. The operational takeaway: don't compete with AI on execution, and don't outsource judgment either — build the muscle for delegation, spec-writing, and fast verification, because that's the real bottleneck now, not raw model capability.
