The models work. Now what.
I'm Spencer. I work on everything else. The integration, the ownership, the operating model that decides whether AI actually gets used. This site hosts some projects, writing, and assorted reference materials that I tend to come back to.
Writing
everything- Outsmarting AISynthetic content is everywhere now. The skill we used to call 'can you spot it' is becoming 'what does it mean that you can't.' A note on detection, skin in the game, and harm reduction.May 20, 2026
- Making Tokens, Pt. 5: The Forward PassAll of the upstream chemistry, physics, and capital comes to rest on a single computation. One forward pass through the trained network. Out the other end: one token. The whole supply chain priced out per unit.April 30, 2026
- Making Tokens, Pt. 4: A City's Worth of PowerA frontier training cluster is a small city of compute, with the power draw and water demand of a small city to match. The siting decisions are quietly reshaping the US power grid.April 7, 2026
- Making Tokens, Pt. 3: PhotolithographyEighty rounds of printing patterns thinner than a virus on a single piece of glass, in a room cleaner than any operating theater on earth. The most complex object humans make at scale.March 10, 2026
- Front Row at the Changing EconomyWhy I want to spend the next decade inside the rooms where AI is being deployed into the real economy, and what it looks like from there.February 15, 2026

- Energy intensity
- ~110 kWh per kg of poly-Si
- Output purity
- 99.9999999% (9N)
- Global output
- ~600 kt / year
- Electronics share
- ~10% (rest goes to solar)
A roughly 200x value-add by mass: quartz sand at $0.10/kg becomes polysilicon at $20-30/kg.

Ask it anything. It knows me.
The little pill in the corner is an AI that knows my background, my writing, and my calendar. Cold email is dead. Ask the website.
