互联网第一条信息发出57周年：UCLA教授克莱因罗克谈适应技术变化之道
10月29日是互联网第一条主机间信息发出57周年：1969年10月29日晚，加州大学洛杉矶分校（UCLA）教授 Leonard Kleinrock 带领团队，从该校 Boelter Hall 3420 室向斯坦福研究所（SRI）的终端发送登录指令「LOGIN」，系统在送出前两个字母「LO」后崩溃，修复后完整送达。UCLA 新闻室在57周年之际专访了 Kleinrock。
Kleinrock 现年92岁，是 UCLA Samueli 工学院计算机科学杰出教授，至今仍在 Boelter Hall 工作，办公室离当年发出第一条信息的实验室只有几步之遥。他1962年的博士论文以数学排队论论证资源共享式网络的可行性，为分组交换与后来的互联网奠定了理论基础；UCLA 随后成为 ARPANET 的第一个节点。
「保持好奇，拥抱机会，不要害怕改变方向；无论做什么，都要把它做好。」谈到如何面对技术变革，Kleinrock 这样给后辈建议。他当年的预言多已成真：互联网会像电力一样始终在线、无处不在；他坦言自己没有预见到的是互联网的社会面——他的母亲活到99岁仍在使用互联网。
从电报、广播、座机、计算机、互联网、智能手机，到如今迅速改变人们学习、沟通与工作方式的超级智能（SI），Kleinrock 经历并参与了近一个世纪的技术变迁。在他看来，每一代技术都带来剧烈调整，而适应变化的能力本身，才是穿越变局的长久之计。
57 Years After the Internet's First Message, UCLA's Leonard Kleinrock Shares His Advice for Changing Times
October 29 marks 57 years since the internet's first host-to-host message. On the evening of October 29, 1969, UCLA professor Leonard Kleinrock and his team tried to send the command "LOGIN" from room 3420 of UCLA's Boelter Hall to a terminal at the Stanford Research Institute. The system crashed after delivering just two letters — "LO" — before the full message got through once the network was restored. For the 57th anniversary, UCLA Newsroom sat down with Kleinrock to revisit that night and his remarkably prescient predictions.
Kleinrock, 92, is a distinguished professor of computer science at the UCLA Samueli School of Engineering and still works in Boelter Hall, a few feet from where the "LO" message was sent. His 1962 doctoral work used mathematical queuing theory to show that resource sharing could underpin a new kind of digital network, laying the theoretical foundation for packet switching and, ultimately, the internet. UCLA became the first node on the ARPANET.
His advice for navigating technological change is timeless: "Stay curious. Embrace opportunities. Don't be afraid to change direction. And whatever you do, do it well." Many of his early predictions came true — the internet would be always on and as invisible as electricity. What he missed, he says, was the social aspect: his mother was on the internet until she passed away at 99, and his preschool granddaughter is online too.
From the telegraph, radio and landlines to computers, the internet, smartphones and now super intelligence (SI), which is rapidly reshaping how people learn, communicate and work, Kleinrock has had a front-row seat to nearly a century of technological upheaval — and helped start one of its biggest revolutions. His conclusion: the ability to adapt to change is itself the durable skill.
