Tech Entrepreneurs Return to San Francisco Amid AI Boom.

Tech entrepreneurs who left San Francisco during the pandemic are returning due to the artificial intelligence (AI) boom. The latest wave of AI technology, known as generative AI, has attracted $10.7 billion in funding for startups within the first three months of this year, a thirteenfold increase from a year earlier. The technology is open source, encouraging a sense of community, and "hacker houses" are springing up in San Francisco's Hayes Valley neighborhood. The AI boom is luring back founders of other kinds of tech companies, and Y Combinator is encouraging startups in its program to move to San Francisco.
