Decrypting war, igniting comments
The Computer That Helped Win World War II
The secret war machine that beat Hitler is back—and the comments are fighting over what it really was
TLDR: Colossus, a massive British machine that helped crack Nazi messages in World War II, is being honored as a historic milestone. In the comments, people are split between calling it a true computer, marveling that it was destroyed for being too dangerous, and joking that its legacy somehow led to AI cat videos.
A giant British codebreaking machine from World War II is getting its flowers at Bletchley Park, and the internet has immediately turned a history lesson into a full-on comment-section cage match. The article celebrates Colossus, the room-sized machine built by engineer Tommy Flowers to crack Germany’s far more advanced Lorenz cipher—the eerie "strange new music" radio operators first heard in 1941. In plain English: this was one of the earliest electronic machines used to help read top-secret Nazi messages, and it mattered a lot.
But the real fireworks are in the reactions. One camp is doing the classic internet thing: "Actually..." Commenters are arguing Colossus was not really the kind of all-purpose computer people imagine today, but more of a special machine built for one wartime job. Another group is obsessed with the deliciously spooky detail that the original machines were reportedly destroyed after the war because they were seen as too powerful and dangerous, with retired engineers later rebuilding one from memory like some incredibly British sci-fi side quest.
Then, because no comment thread can stay normal, someone swerved into conspiracy territory about bankers, Ford, and who really enabled Hitler—while another person summed up modern progress as a journey from codebreaking heroics to AI bear videos, deepfakes, and cat clips. The vibe is equal parts awe, nitpicking, dark humor, and "wow, humanity really did all this and this is where we ended up."
Key Points
- •In 1941, British intercept operators detected a new high-speed German encrypted teletype transmission that differed from Enigma traffic.
- •Tommy Flowers built Colossus to help break the new cipher; the article describes it as the first large-scale programmable electronic digital computer.
- •Colossus was installed at Bletchley Park, and the article notes it is being recognized as an IEEE Milestone with a ceremony scheduled for 29 September.
- •The German machine behind the cipher was later identified as a product of Berlin firm C. Lorenz and was codenamed “Tunny” by British codebreakers.
- •John Tiltman, Bill Tutte, and Alan Turing each contributed key analytical steps that helped reveal the machine’s operation and infer settings needed for decryption.
