Frontier AI has broken the open CTF format (the CTF scene is dead)
“AI didn’t just win CTFs—it killed the game. The scoreboard now measures who can prompt best.”
Why It Matters
Concrete cultural/institutional collapse of a core builder/hacker training ground—CTFs shift from artistic human craft, struggle, and technique-sharing to "pay-to-win" AI cheesing, demotivating new builders and eroding security culture. Weird intelligible story of an era ending.
Evidence
kabir.au blog post + HN top discussion (189 pts, recent activity): Frontier models (Claude Opus 4.5, GPT-5.5) + orchestration/agents now autonomously solve medium-to-hard challenges in minutes; scoreboards reward token spend and prompt engineering over human skill; legendary teams disengaging, events shrinking, challenge authors demotivated.
