George Hotz—the hacker who first cracked the iPhone at age 17 and reverse-engineered the PlayStation 3 before Sony sued him for it—published a blog post Sunday arguing that mass adoption of AI coding agents will end in disaster, or at least close to it.

- Karpathy, who had been skeptical of agents earlier in 2025, reversed his position after new model releases and joined Anthropic's pre-training team on May 19—five days before Hotz published
- Hotz now places himself in what he calls the "LeCun/Marcus camp"—referring to Yann LeCun, Meta's chief AI scientist, and Gary Marcus, a longtime LLM skeptic
- The bottom performers won't have that self check," he writes—and they're the ones using agents to produce 10 times their previous output
Summary
George Hotz, the hacker behind the first iPhone jailbreak and PlayStation 3 crack, published a blog post Sunday calling AI coding agent adoption "one of the most costly mistakes in the field's history. His core argument: high performers can spot bad agent output, but weaker engineers can't—and it's the weaker engineers producing ten times the volume, degrading average code quality at scale. The post arrived five days after Andrej Karpathy joined Anthropic's pre-training team with the opposite view, marking a clear split among serious engineers on whether AI agents work. George Hotz—the hacker who first cracked the iPhone at age 17 and reverse-engineered the PlayStation 3 before Sony sued him for it Andrej Karpathy May 19, 2026. Hotz didn't reach his conclusion from the sidelines.
