Large Learning Models Are An Unfortunate Detour in AI

Artificial Intelligence}

For decades, computer scientists have struggled to construct systems possessing artificial general intelligence (AGI) that rivals the human brain—including the ability to use analogies, take into account context, and understand cause-and-effect. Marvin Minsky (1927–2016) was hardly alone in his overly optimistic 1970 prediction that, “In from three to eight years we will have a machine with the general intelligence of an average human being.” AGI turned out to be immensely more difficult than imagined and researchers turned their attention to bite-size projects that were doable (and profitable). Recently, large language models (LLMs) — most notably OpenAI’s GPT-3 — have fueled a resurgence of hope that AGI is almost here. GPT-3 was trained by breaking 450 gigabytes of text data into Read More ›

Matthew Walker is a professor of neuroscience and psychology and founder of the Center for Human Sleep Science at the University of California, Berkeley. He has become famous for his book and a TED talk promoting the importance of sleep for health and performance. He even got a job at Google as a “sleep scientist.” Walker has a receptive audience because he is entertaining and his arguments make sense. In one of his books, Walker used a graph similar to the figure below to show that a study done by other researchers had found that adolescent athletes who sleep more are less likely to be injured. The figure is compelling, but there are several potential problems. The hours-of-sleep data were based on 112 responses to an online Read More ›
