OpenAI Hired the Guy Anthropic Screwed Over. It's the Smartest Move in AI This Year.

Sam Altman didn't just hire Peter Steinberger. He bought the loyalty of 247,000 developers who now have a reason to hate Anthropic.

On February 15th, 2026, Sam Altman posted seven sentences on X that changed the AI landscape more than any product launch this year:

"Peter Steinberger is joining OpenAI to drive the next generation of personal agents. He is a genius with a lot of amazing ideas about the future of very smart agents interacting with each other to do very useful things for people."

The sound of Anthropic's developer relations team collectively swearing into their monitors.

Because this wasn't just a hire.
