0:00 The first message ever sent across what would become the internet wasn't some grand, poetic line.0:07 It was just two letters: L-O.0:09 Right.0:10 And the person who sent it, Charley Kline, is a perfect example of what we talked about last week, Admin, on "Unsung Architects." He's the person at the keyboard for a world-changing moment, but his name is almost completely unknown.0:27 So take us there.0:29 It's October 29th, 1969.0:30 What's the scene?0:32 Is this a big media event?0:34 Oh, not at all.0:35 It's the opposite.0:36 It's late, about 10:30 at night.0:39 You've got a student programmer, Charley Kline, in a lab at UCLA.0:44 He's working for his professor, Leonard Kleinrock.0:47 Their job wasn't to make history—it was to stress-test this new military network, the ARPANET.0:55 They were supposed to find the breaking points.0:58 And on the other end of the line?1:01 Another programmer, Bill Duvall, at the Stanford Research Institute, or SRI.1:06 And they're connected by two things: this brand new, unproven computer link, and a regular old telephone line with headsets.1:16 They're literally talking to each other as this happens.1:20 So it's just a diagnostic test.1:22 What were they even trying to do?1:25 The simplest thing imaginable.1:27 Kline was trying to log in to the Stanford computer from his computer at UCLA.1:33 The command for that was "LOGIN".1:36 That was the whole goal.1:38 Just make one machine talk to the other.1:41 Okay, so Kline is at the keyboard.1:43 He has Duvall on the phone.1:45 What happens?1:46 It's almost like a little play.1:49 Kleinrock, the professor, described it perfectly.1:52 Charley types the letter 'L'.1:55 He says into his headset, "Did you get the L?" And from Stanford, Duvall's voice comes back, "Got the L." Okay, so far so good.2:04 Yep.2:05 Then Charley types the 'O'.2:07 He asks, "Did you get the O?" Duvall replies, "Got the O." The log from the time literally shows the letters "l-o" being received.2:16 And then...2:17 Charley types the 'G'.2:19 And?2:19 And the system crashes.2:21 The whole thing just goes down.2:23 Wait—really?2:24 So the first message ever sent on the precursor to the internet was an ACCIDENT?2:30 A beautiful, perfect accident.2:33 The first message was "LO" because that's the point where the machine failed.2:39 As Kleinrock later said, the internet's first message was, presciently, "Lo and behold!" It's so different from other "firsts" in history.2:49 I'm thinking of Samuel Morse and the first telegraph message—"What hath God wrought." That was so...2:57 prepared.2:57 So monumental.2:58 Exactly.2:59 This is the pattern of deep innovation versus a demonstration.3:04 Morse was showing off something that was finished.3:08 Kline was part of an experiment to see if a thing would even work.3:13 And in that context, a crash isn't just a failure—it's data.3:17 It's the most valuable thing they could have learned.3:21 They found a bug.3:22 So the messy, broken result was actually the point.3:26 In many ways, yes.3:28 It's a story we see over and over.3:30 The real breakthrough doesn't look clean.3:33 It's a contaminated petri dish that leads to penicillin.3:38 It's a system crash that becomes the birth of a global network.3:43 The significance only becomes clear in hindsight.3:46 So did they ever get the full message through?3:50 They did.3:50 About an hour later, after they got the system back up, Kline successfully sent the full "LOGIN" command.3:58 But history, correctly, I think, remembers the "LO." Because that's the more honest story.4:05 It's the truer story.4:07 It tells you that the internet wasn't born in a flash of genius.4:12 It was built.4:13 It was debugged.4:14 It was pieced together by quiet, diligent people like Charley Kline, sitting in a lab late at night, just trying to get one thing to work.4:24 He's the hands, not the visionary.4:27 He's the one actually doing the work.4:30 And his story is the story of how so much of our world is actually made.4:35 It makes you wonder, you know?4:38 Who is the Charley Kline of today?4:40 Sitting in some lab, typing a command that just failed...4:45 in a way that will completely redefine our world in twenty years.
