The article challenges the notion that scientific ideas are becoming harder to find, calling skeptics cowards. The author recounts a conversation with a distressed student who believed all easy ideas had already been explored. He reflects on his own doubts about being born too late to discover low-hanging fruit, recalling that past breakthroughs like heliocentrism or germ theory seemed obvious only in hindsight.
While scholars like Scott Alexander, Holden Karnofsky, and Dean Keith Simonton argue that progress is slowing due to increasing specialization, larger teams, and the complexity of modern science, the author rejects this pessimism. He asserts that the belief in human ingenuity must be defended against narratives that discourage exploration. Two cognitive biases are identified: ideas seem obvious in retrospect, and the effort required to innovate always feels daunting.
Historical parallels, such as 19th-century claims that physics was nearing completion, show past overconfidence in reaching intellectual limits. The author insists that fear of difficulty should not justify giving up, urging continued effort to uncover remaining truths. He concludes that the human spirit thrives on attempting the seemingly impossible, and that doubt itself should not halt discovery.
