Mitchell Hashimoto, founder of HashiCorp and creator of Vagrant, Terraform, and Vault, posted a thread on Twitter that detonated on Hacker News: "I strongly believe there are entire companies right now under heavy AI psychosis and it's impossible to have rational conversations about it with them."

This struck a nerve because it names a phenomenon spreading through the software industry: not AI itself, but the blind faith in AI replacing engineering judgment.

Three Symptoms of AI Psychosis

1. Decision-making outsourced to AI. Product direction, architecture choices, tech stack—all decided by ChatGPT or Claude. One commenter shared: "I know someone who used AI to migrate their company's database from Oracle to MariaDB. He didn't even know the difference between the two."

2. "Bugs don't matter, AI will fix them." This is the engineer's nightmare. In the AI fever, shipping broken code is considered normal because "AI agents can fix bugs quickly, at a scale humans can't." Mitchell specifically called this out: "They say quality doesn't matter because the agents will fix bugs so fast." This is precisely the anti-pattern Rich Hickey warned about in "Simple Made Easy."

3. Rational conversation becomes impossible. When you point out risks, you're dismissed as "not understanding AI" or "being too conservative." Any questioning is framed as resistance to progress. The premise of discussion itself has been corrupted.

The Rise of AI Rescue Consulting

One of the most prescient HN comments predicted that AI Rescue Consulting will become the next high-value consulting niche—like incident response in cybersecurity, but for companies whose AI-generated infrastructure has collapsed. "Purely AI generated companies are going to run into intractable problems. Things will spiral. Consultants will be brought in to fix them—at a premium."

Another commenter noted: "Maybe this is what will turn software engineering into an actual Engineering field. Right now, prompters are setting up entire company infrastructure. There will be a lot of messes to clean up."

The Warning Comes from Someone Who Knows

Mitchell Hashimoto is no Luddite. The tools he built—Vagrant, Terraform, Packer, Vault—are themselves pioneers of infrastructure automation. His concern comes from deep engineering experience: automation should eliminate tedium, not eliminate thinking. When you outsource understanding, you lose not just quality, but the ability to rescue your system when things go wrong.
