AI-produced code is good but it's not so good that it can replace hand-crafted (or heavily supervised) code written by the type of engineer who works at Cloudflare.

What's really happening is that a few employees realized they can game the system by turning on a firehose of AI slop and pushing 10x the LOC than any other engineer (with or without AI), because there's no one to tell them to stop, and in fact with a management that actively encourages this.
