Matt Pocock: With AI, both waterfall and agile get better — plan in code, not text

Responding to Gergely Orosz, Matt Pocock argues Big Upfront Planning works with AI only at the right fidelity. People spending a month planning in text (e.g. /wayfinder) often end up disappointed — plan with prototypes instead. Agents make building prototypes and gathering early feedback easier than ever, so agile is also enhanced by AI: both paradigms win, the key is planning in code rather than prose.
