Curing cancer, going to the Mars, solving hundred-year-old mathematics puzzle… Humanity’s biggest challenges take years, decades or beyond. But today’s AI operates in short context window that lasts minutes, hours or days.

Chengxi Taylor is Co-founder & President of General Reasoning, a London-based AI research company. Her work focuses on long-horizon, non-stationary decision-making: building AI systems that can pursue a strategy over long period of time (years, decades and beyond) while adapting as the world changes.

She believes long-horizon thinking is not just a technical challenge, but a mindset. It’s about rebuilding the ability to sustain purpose and progress over time, in machines and in ourselves.
