Who they are
Vint Cerf (1943– ) is an American computer scientist who in the 1970s, with Bob Kahn, co-designed and developed the TCP/IP protocol — a universal technical standard specifying how data packets should be split, transmitted, and reassembled among different types of originally mutually incompatible computer networks — a protocol that thereafter became the core underlying architecture by which the global internet could connect and interoperate countless originally independent local networks of different technical standards into a unified whole, and Cerf is thereby, with Kahn, honored as a "father of the internet." The most forward-looking idea in the design of TCP/IP was deliberately designing the network itself to be as "simple and dumb" as possible, placing the complex intelligent processing functions of data checking, error correction, and flow control as far as possible on the terminal devices at the network’s edge rather than concentrating them at the network’s central nodes — this "edge intelligence, core simplicity" architectural design philosophy was proven to have strong scaling elasticity and compatibility, letting the internet keep absorbing and integrating over the decades after all manner of wholly unforeseen new network technologies and application forms without tearing down and completely redesigning the underlying protocol architecture. Cerf thereafter long held at Google the highly personal job title of "Chief Internet Evangelist," continuing to actively drive the further expansion and technical evolution of global internet infrastructure.

Key stories
Making a "Dumb" Network All-Capable
In designing TCP/IP, Cerf and Kahn deliberately chose to keep the network core as simple and plain as possible, responsible only for basic packet forwarding, while delegating the complex processing logic of data checking, error retransmission, and flow regulation as far as possible to the terminal devices at the network edge — this "simple core, intelligent edge" design philosophy was thereafter proven to have strong scaling elasticity, letting the internet keep absorbing and integrating over the decades all manner of wholly unforeseen new technologies and application scenes without tearing down and redesigning the underlying architecture.
"Chief Internet Evangelist"
Cerf thereafter long held at Google the highly personal and exceedingly rare job title of "Chief Internet Evangelist," continuing to actively advocate and drive the further spread and expansion of internet infrastructure worldwide, including exploring strikingly forward-looking long-term topics such as an interplanetary internet communication protocol, and this distinctive professional role also reflects from the side his lasting sense of mission, beyond mere commercial interest, toward the internet he himself helped lay the foundation of.
