I read the multi-agent development paper and the penny dropped hard: the weird bugs I kept seeing in vibe-coded PRs weren't AI hallucinations. They were race conditions between agents. Same as Rust and mutexes — just one abstraction higher, with no compiler to warn you.
Three AI-generated PRs. Three AWS API keys sitting in the code. Three times I approved them because the tests passed. The security problem with vibe-coding isn't the model — it's how your attention shifts when you're reviewing code a human didn't write.
Vibe-coding is fantastic — until your project has real users. Here's the concrete difference between how I use AI for experimentation versus how I use it when production is on the line.
