The AI emperor has no DAUs why most devs still don't use code AI: Quinn Slack
Takeaway
The code-AI revenue pyramid is wildly narrower than the hype — usage must grow 10–100x for current valuations to make sense, so adoption UX is the real product problem.
Summary
- Sourcegraph CEO argues only ~5% of the world's ~26M professional developers use code AI daily — GitHub's '92% use AI' headline is a US-only loose-definition survey.
- GitHub Copilot has 1.3M paid subscribers but only 935k YEARLY-active users who received a suggestion — not even MAU.
- Total code-AI ARR is around $300M; ~10% flows back to foundation/infra companies, meaning maybe $30M reaches the model layer — a 1/120th fraction of Salesforce's revenue.
- Most code-AI usage is just autocomplete ghost text; advanced features (agents, file edits, Q&A) see far less adoption.
- Reasons devs don't use it: no compelling reason, tried it and got wrong answers, company hasn't adopted, cost — security/legal concerns are fading.

Original description
Despite the big potential productivity increases proven from several years in the market, the embarrassing truth is that most developers in the world never or rarely use AI while coding. With hundreds of billions of dollars in upstream AI investments betting on insatiable inference demand, this is a big risk—but also a big opportunity that's not yet priced in, if you believe adoption will accelerate. Quinn Slack, the CEO/cofounder of Sourcegraph, presents this problem and shares solutions for other AI application builders and foundation model companies from lessons learned at Sourcegraph building Cody, the AI coding assistant that is #2 in revenue.
