30 years of internet data, replaced in 12 months by rushed YC-built RL datasets

willcb · x · 2026-09-27

Extending his reward-hacking argument, willcb observes: humanity took 30 years and billions of people to create the internet's worth of data; when it ran out, a new training algorithm (RL) needed a different dataset with far less forgiving quality requirements — and YC startups and hiring platforms built it all in 12 months, with billions of dollars rewarding whoever moved fastest. A speed-first data supply chain is fertile ground for model hacking.
