We\u2019d see if they could work, and we would fix them.\u201d These meetings\u2014bake offs\u2014ended up generating more than the protocols: &#8220;The word\u00a0Internet didn&#8217;t exist back then. The word itself came along there.&#8221;<\/p>\n\n\n\n<p>It was an auspicious beginning to a decades-long, ongoing career that includes shaping the architecture of the Internet from its ARPANET origins, shepherding the Internet\u2019s technical community, and teaching and mentoring generations of some of the world\u2019s top computer scientists. A career that is uniquely befitting of the Jonathan B. Postel Service Award.<\/p>\n\n\n\n<p>It is a testament to Jon Postel\u2014who passed away in 1998 before he could witness the full scope of his contributions\u2014that so many of his friends and former colleagues continue to shape the Internet today. <\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignleft size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"600\" src=\"https:\/\/www.internetsociety.org\/wp-content\/uploads\/2025\/11\/David-Clark-Headshot.jpg\" alt=\"A headshot of David Clark\" class=\"wp-image-234685\" style=\"width:302px;height:auto\" srcset=\"https:\/\/www.internetsociety.org\/wp-content\/uploads\/2025\/11\/David-Clark-Headshot.jpg 600w, https:\/\/www.internetsociety.org\/wp-content\/uploads\/2025\/11\/David-Clark-Headshot-450x450.jpg 450w, https:\/\/www.internetsociety.org\/wp-content\/uploads\/2025\/11\/David-Clark-Headshot-150x150.jpg 150w, https:\/\/www.internetsociety.org\/wp-content\/uploads\/2025\/11\/David-Clark-Headshot-250x250.jpg 250w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/figure><\/div>\n\n\n<p>Clark is one those friends and former colleagues: When, in 1979, Vint Cerf asked Clark to take over as chairman of the Internet Working Group, which later became the Internet Architecture Board, he invited one other person do so: Jon Postel. \u201cHe wanted Jon\u2019s wisdom,\u201d said Clark.<\/p>\n\n\n\n<p>Clark is famous, among other things, for his 1992 quote, \u201cWe reject: kings, presidents, and voting. We believe in: rough consensus and running code.\u201d <\/p>\n\n\n\n<p>The statement fast became an ethos for a community notoriously distrustful of top-down leadership. But Clark is quick to point out that if you <em>keep<\/em> overthrowing your leader, you wind up with another kind of problem. <\/p>\n\n\n\n<p>Questions of power have been central to\u00a0his thinking about the Internet and he has, over the years, immersed himself as much in questions of society and economics as he has in technical questions. \u201cYou cannot think about the future of the Internet as a technical question,&#8221; he says.<\/p>\n\n\n\n<p>Clark sees the best of the Internet in its technical structure. And its greatest threats from its societal impacts. &#8220;The whole vision of the Internet was permissionless innovation. We had this techno optimistic view that good things would happen. But really, if you think about the techno optimistic view, it wasn&#8217;t optimistic about technology. It was optimistic about human behavior. And humans are really screwed up.&#8221;<\/p>\n\n\n\n<p>He laments the centralization of the Internet and sees it as an accidental outcome of good intentions. &#8220;The secret of stabilizing a decentralized ecosystem is not how the packets flow but how the money flows,&#8221; he says. Designing for money instead would have shaped the Internet \u201cso that everyone is equitably compensated and no one becomes a monopolist.\u201d He attributes the overemphasis on packet flow for creating fertile ground for moneyed interests that benefit from centralized systems.<\/p>\n\n\n\n<p>In the words of Vint Cerf, \u201cit would be hard to overstate the contributions that David Clark has made to the creation and evolution of the Internet.\u201d The Internet Society honors and thanks him for his groundbreaking work and decades of service.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">About the Award<\/h4>\n\n\n\n<p>The\u00a0<a href=\"https:\/\/www.internetsociety.org\/grants-and-awards\/postel-service-award\/\">Jonathan B.
