The CEO of Anthropic has warned that AI will lead to a mix of high growth and high unemployment, with software costs potentially decreasing to zero. There are concerns about the rapid development of AI, with some warning of significant risks and potential consequences, including the automation of white-collar work and "civilization-level" risks. The use of Anthropic's AI technology is also facing opposition, with reports of a dispute with the US government and a directive from a prominent figure to stop using the company's technology.
