My tests said 90%. They were measuring the wrong thing.
I built a chord recogniser for AnyChord, my new app, and generated my own ground truth to score it. It reached 89.7%. Then I found the mistake it made on every real record, and understood that my test suite could not see that mistake at all.

I have played guitar for thirty years. I still take lessons.

I complained about AI slop. Then I built a tool that rewrites AI text.

The crawl deal is broken
Bots passed humans on Cloudflare's network in May, and the internet spent last week arguing about a 1,000x forecast. That is the wrong number.
