It's a symbolic moment: one of the network's founding architects steps back just as AI reshapes the internet he helped build. One of the people who made the modern internet possible is stepping back. **Vint Cerf**, 83, is **retiring from Google**, where he spent more than 20 years as its **"chief internet evangelist,"** [TechCrunch reported](https://techcrunch.com/2026/06/30/the-father-of-the-internet-is-finally-retiring/). It's a small personnel change with a large symbolism: a **founding architect** of the internet is bowing out as the network enters its **AI age.** ## What he actually built In the 1970s, Cerf and **Robert Kahn** designed **TCP/IP** — the **Transmission Control Protocol / Internet Protocol** — a set of rules that solved a deceptively hard problem: how to get **different, incompatible computer networks** to talk to one another reliably. That work is why we call him, alongside Kahn, a "**father of the internet.**" Think of TCP/IP as the internet's **postal system.** **IP** is the addressing — it figures out how to route a packet of data to the right place anywhere on Earth. **TCP** is the delivery guarantee — it makes sure the pieces arrive, in order, and nothing is lost. **Every** email, video call, web page and financial transaction you make travels on top of these rules. They are the **plumbing beneath the entire digital economy.** ## A life at the internet's core Cerf's career traces the internet's whole arc. He worked on the research that grew out of **ARPANET**, the US defense network that preceded the internet; managed protocol development at the defense research agency **DARPA**; and later helped build one of the **first commercial email services.** For his TCP/IP work, he and Kahn won computing's top prize, the **Turing Award (2004)**, and the **Presidential Medal of Freedom (2005)**, [per the Internet Hall of Fame](https://www.internethalloffame.org/vint-cerf/). He also helped **govern** the internet — co-founding the **Internet Society** and chairing **ICANN**, the body that oversees domain names — working to keep the network's core **independent** of any single government or company. ## Why his exit resonates now Cerf's retirement marks the **founding generation stepping back** — and the internet they built on principles of **openness, interoperability and shared control** looks very different today. The modern web is **concentrated**: a handful of giant companies dominate traffic, data and attention. **Governments** increasingly wall off their slices of it. And now **artificial intelligence** is rewiring how information is created and flows across it. Cerf has been a **candid voice** on these tensions — arguing for an **open** internet and warning about the risks of **centralization.** His departure lands exactly as the industry debates how the **open protocols of the 1970s** should evolve in an era of AI, surveillance and platform power. ## Why it matters For **Boursel's readers**, this isn't nostalgia — it's infrastructure. The internet is the **backbone of the global economy**: every app, marketplace, bank and connected device runs on the foundation Cerf helped lay. His legacy is the reminder that today's trillion-dollar digital businesses sit atop a **non-commercial, open standard** built to **share information and survive failure** — not to be owned. As the founders who insisted on that openness retire, the **open question** they leave behind is whether the internet's next era keeps those values, or trades them away. In Cerf's own recurring phrase about the work of building the internet: **"We still have a lot of work to do."** ## Sources - [The 'Father of the Internet' is finally retiring](https://techcrunch.com/2026/06/30/the-father-of-the-internet-is-finally-retiring/) - [Vint Cerf — Internet Hall of Fame](https://www.internethalloffame.org/vint-cerf/)
