AI writes code: Kenton Varda on trust, review, and why Workers is the best AI platform

In this episode, host João Tomé is joined by Kenton Varda, Principal Engineer at Cloudflare, for a wide-ranging conversation about AI, code, and the evolution of Internet development.

Kenton shares how a real-world project shifted his view from AI skepticism to seeing the promise of AI-assisted coding, while emphasizing the need for strong human review, especially for security. The episode also dives into the architecture of Cloudflare Workers and its first months, Durable Objects, and the vision of the Internet as one programmable computer: “the network is the computer”.

Looking ahead, Kenton predicts a new era of developers powered by AI assistants — building more custom apps than ever — and explains why Cloudflare Workers is built to support that future.
