Episode notes
Prototype With AI Before Asking For Engineering
- Use AI to prototype, not just write docs, so product decisions become based on working demos rather than abstract proposals.
- Duolingo product managers deliver AI-built prototypes that reveal whether a feature actually teaches better before engineering buy-in.
Make Companywide AI Experimentation Mandatory
- Democratize AI skills across the company so non-engineers can experiment: run company-wide vibe-coding days and maintain Best AI Practices channels.
- Share both successes and failures publicly to accelerate peer learning.
How Two Employees Built Chess In Six Months
- Two non-engineers built Duolingo's chess course in six months by vibe-coding prototypes and iterating with AI.
- They trained AI on an online chess puzzle database, improved generation, and produced a mobile prototype that scaled to production.
