Share of production code generated by AI vs. written by humansContested: Amodei cites high internal use at Anthropic, but there is no verified industry-wide 90% figure and independent analyses dispute it
Verified blind: DeepSeek V4 + Grok — agree
Met if, broadly across software, AI is generating ~90% of code by late 2025; failed if human-written code stays the clear majority of production software
