Amodei 90%-of-code claim — September 2025 checkpoint context

Dario Amodei stated in March 2025 that AI could write 90% of code within three to six months. By the September 2025 checkpoint, an arXiv study estimated AI wrote 30.1% of Python functions from US contributors as of December 2024, and Microsoft reported 20–30% of its code was AI-generated. No verified industry-wide 90% figure surfaced by that checkpoint, per a Skeptics StackExchange survey.
