AI is reviving San Francisco's tech scene. Welcome to 'Cerebral Valley.'

In a sign of the times, the Hillsborough mansion recently changed its name from Neogenesis to AGI House. AGI is short for "artificial general intelligence," a phrase popularized by OpenAI to describe the idea of AI that is smarter than a human. OpenAI argues that tools like ChatGPT, which can instantly answer questions or generate text like software code and college essays, or the text-to-image generator DALL-E, can respond to a user's natural language prompt, as steppingstones toward superhuman AI. The term "AGI" has become a watchword for proponents who share the belief that this technological wave of AI will transform the internet.
