Perplexity CEO says this 'Beautiful Mind' habit quietly kills startups

Perplexity CEO Aravind Srinivas says his hardest founder lesson was unlearning the academic instinct to perfect an idea on a whiteboard before building. Movies like "A Beautiful Mind" sell a myth of instant genius, he argues, but plans only feel safe—they produce no real information. His fix: ship small experiments fast, watch what users actually do, and iterate. Effort exposed to reality, not polished planning, is what actually teaches you anything.
