In March the company’s alignment lead called it a present phenomenon. Here its co-founder quotes a probability and a date: Jack Clark put the odds of recursive self-improvement arriving by the end of 2028 at 60%, grounding the number in hundreds of public data sources (X), where in January he had reported only early signs of AI doing components of AI research. The figure lands a day after OpenAI’s president put the distance to AGI at 80% and a month after the AI 2027 authors pulled their timelines forward; the lab’s own institute made the evidential case in June in When AI builds itself, which supersedes this item.
