One AI-written bug a day

Somewhere in the last two years you stopped reading code and started approving it. This is one snippet a day to find out how cooked you are.

The brain rot is measurable

19%

Slower when using AI

20%

Faster, they thought

In a randomized trial, experienced developers took 19% longer to finish real tasks when they used AI. Afterwards, they guessed it had made them 20% faster. Nobody noticed at the time. If you are sure this does not apply to you, so were they.

  1. EasyDays 1-3Off-by-one. Wrong operator. A branch nothing can reach.
  2. MediumDays 4-9Bad edge cases. Unguarded nulls. Mutating a list while looping it.
  3. HardDays 10-20Async races. Silent coercion. An early return that eats the rest.
  4. BrutalDay 21+Clean, well named, confidently commented. The comment is lying to you.
