Paul Graham says formidable founders drive trillion-dollar companies, while YC’s core startup lessons remain unchanged after 21 years.
At YC’s original Mountain View office, Paul Graham reflects on the accelerator’s 21 years and argues that today’s startups are tackling more ambitious problems, from cancer research to intercontinental cargo rockets. He says founders need ambition because building a company is grueling, but day-to-day they are usually driven less by future wealth than by fear of failure and the urgent problems in front of them. The strongest founders are “formidable”: people who get what they want. Graham also explains that OpenAI made a new kind of Google possible by changing how people access information, and says AI’s surprising path began with human-like, plausible errors rather than simpler, reliable intelligence. AI has not changed the fundamentals: startups still need to ship quickly, though GPU and token bills can now reach tens of thousands of dollars a day. He recounts how YC began as an angel-investing experiment that became a summer startup batch, and says its model has changed little as it grew.
