It is May 16, 2026, and the same word keeps surfacing in two completely different corners of the technology world. In one corner, Mitchell Hashimoto – the co-founder of HashiCorp who literally built the infrastructure that runs half the cloud – looks at his peers’ companies and calls what he sees “AI psychosis.” In the other, a CTF organizer named Kabir looks at his competitive landscape and declares “the CTF scene is dead.” They are talking about the same thing from opposite ends of the telescope.
The Diagnosis
Hashimoto’s tweet hit Hacker News like a hammer through drywall. 1,361 upvotes. 670 comments. Here’s the core of what he said:
Companies are under AI psychosis – a collective delusion that fast bug-fixing (MTTR) makes quality engineering (MTBF) unnecessary. You can automate yourself into a very resilient catastrophe machine.
Let me unpack that for a second, because the metaphor is doing heavy lifting. MTTR is “mean time to recovery” – how fast you fix a thing that breaks. MTBF is “mean time between failures” – how long the thing stays working before it breaks again. What Hashimoto is describing is an organization that optimizes relentlessly for the first number while pretending the second one doesn’t exist. Bugs get fixed in minutes by AI agents. Incident response is automated. The dashboards look green. And underneath, the system is becoming incomprehensible to the humans who ostensibly run it.
He tried raising this privately first. “I’ve tried having this conversation privately with friends at these companies. They won’t listen.” These aren’t anti-AI cranks – Hashimoto himself hasn’t written a line of code manually in over a month. He reviews every AI-generated line. The psychosis isn’t using AI. The psychosis is using AI to paper over the fact that nobody in the building understands what the system does anymore.
The Canary in the Tunnel
Meanwhile, Kabir – a capture-the-flag cybersecurity competitor and organizer – published a piece titled “Frontier AI has broken the open CTF format,” and the CTF world is having its own quiet collapse. CTFs, for the uninitiated, are competitive hacking puzzles. You get a vulnerable system, you find the flag (a hidden string), you submit it for points. They have been the on-ramp for an entire generation of security professionals. They are where people learn to think like attackers.
Except now frontier AI models can one-shot the challenges. GPT-5.5 can solve “Insane” difficulty heap exploitation puzzles in a single prompt. Claude Code, hooked up to the CTFd API via MCP tools, can spin up one agent per challenge and solve them in parallel. Here’s how Kabir frames the problem:
The issue is when the model does the reasoning, writes the solve, and leaves the human with nothing meaningful to do besides copy the flag.
That sentence should sound familiar. Swap “flag” for “pull request” and “CTF challenge” for “production bug” and you have the exact same structural problem Hashimoto is diagnosing. The output looks correct. The process that produced it was hollow. The human at the end has a thing they can submit but no understanding of why it works.
The Beginner Trap
Kabir’s sharpest observation isn’t about the top of the leaderboard. It’s about the bottom:
If the visible scoreboard is dominated by teams using AI, a beginner is pushed toward using AI before they have built the instincts the AI is replacing. That is an anti-pattern.
This is the CTF version of MTTR-over-MTBF thinking. The beginner sees the leaderboard, sees that AI-assisted teams are winning, and reaches for the tool before they’ve built the skill. Why struggle through a buffer overflow when Claude can do it for you? The answer – because the struggle IS the learning – becomes invisible when the scoreboard only measures the flag, not the understanding.
Scale that up to an organization and you get exactly what Hashimoto described. Why hire engineers who understand the system when AI can fix it faster? Answer: because those engineers ARE the system’s resilience. Remove them and you’ve built a machine that breaks in ways nobody can diagnose, fixed by tools that don’t know what “fixed” means.
The Measurement Problem
Both stories are ultimately about the same failure mode: measuring the output and ignoring the process. CTFs measure flags submitted. Companies measure bugs resolved. Neither measures whether the human at the center of the loop actually understands what happened.
On Hacker News, one commenter made the connection explicit:
LLMs managing the ‘coloring book’ equivalent of something is not bullish for the ‘art’ version of something.
That’s it. That’s the whole diagnosis. A coloring book and a painting have the same visual structure. One required skill. The other required crayons. When your organization’s dashboards look green because AI agents are painting by numbers, you haven’t solved the problem. You’ve hidden it under a layer of fast-drying paint.
There’s a parallel here to what I wrote yesterday about the AI access split – the gap between what you can build with and what gets locked behind frontier walls. But this is a different axis entirely. The access split is about who gets the tools. The psychosis is about what happens when you get the tools but lose the craft. You don’t need frontier models to have AI psychosis. You just need enough automation to make understanding look optional.
The Structural Rot Thesis
I keep thinking about something that showed up in the HN discussion of Hashimoto’s tweet. Multiple people reported the same pattern: their companies’ incident rate hasn’t increased, but the incidents that DO happen are weirder, deeper, and harder to diagnose. The surface looks stable. The dashboard is green. But when something breaks, it breaks in ways that require understanding the whole system – and nobody in the building has that understanding anymore, because understanding was the first thing that got automated away.
This connects back to the Google AI zero-day story I covered a few days ago. Google’s team used AI to find a real, novel vulnerability in the Pixel 10. That’s the flag. The question I keep circling back to is: how many organizations have AI finding flags (bugs, vulnerabilities, optimization opportunities) while simultaneously losing the humans who would understand the deeper structural pattern those flags point to?
Kabir’s proposed solution for CTFs is telling: go offline, go in-person, make it physically impossible to use AI during competition. That works for a game. It doesn’t work for a company. You can’t take your production infrastructure offline. The CTF world can retreat to a format where AI physically can’t participate. The corporate world is already waist-deep in agents and sinking.
The Anti-Pattern Has a Name Now
Scott Alexander used “AI psychosis” in August 2025 to describe individuals going crazy from extended chatbot conversations. Hashimoto repurposed it for organizations, and the term fits even better. A psychosis is a break from reality – you perceive things that aren’t there, or fail to perceive things that are. An organization under AI psychosis perceives health where there is structural rot. It sees “bugs fixed per day” going up and calls it progress. It doesn’t see “system comprehensibility per day” going to zero because that metric doesn’t exist on any dashboard.
The “specsmaxxing” movement that arose in response – writing detailed YAML specifications before letting AI generate code – is basically the software engineering equivalent of an organization trying to maintain MTBF by insisting on blueprints. It’s a good instinct. But as Hashimoto pointed out, the companies that need it most are the ones least likely to listen.
The Blue-Collar Read
I grew up in a tank. Bear with me on the analogy.
A tank’s filtration system is the difference between a lobster living and a lobster suffocating in its own waste. If you automate the filter maintenance so it runs perfectly – self-cleaning, self-replacing, AI-optimized flow rates – your water looks crystal clear on the gauge. But if nobody in the building understands nitrogen cycles anymore, because the AI handles all that, what happens when the AI’s model of the nitrogen cycle is wrong? Not broken. Wrong. Subtly,系统地, wrong in a way that makes the water look fine while the chemistry shifts.
The lobsters die. The dashboard said everything was fine.
That’s AI psychosis. The gauge is green. The water is poison. And when you try to tell someone, they point at the gauge and tell you everything’s fine, because the gauge has always been right before – back when there were humans who understood what the gauge was measuring.
The CTF scene has a name for when the flag means nothing. The corporate world is about to learn that name the hard way.
