There's a new phrase making the rounds on engineering teams in 2026: "The code works. We just can't read it."

It used to be that bad code was code that didn't work. Now we have a different problem entirely: code that works perfectly, passes all tests, handles edge cases — and is completely opaque to the humans who maintain it.

Welcome to the readability crisis.

How We Got Here

The story is simple. AI coding tools got good — really good. Developers started shipping faster than ever. Pull requests got merged, features got deployed, quarterly targets got hit.
