Investor David B. McMillan argues that the market is overly optimistic about the arrival of artificial general intelligence (AGI) and underestimates companies that improve productivity by adopting existing AI tools. He believes true AGI is unattainable with current computing technology and that progress in large language models (LLMs) will plateau, reducing returns on AI infrastructure investments. McMillan sees strong buying opportunities in companies like Berkshire Hathaway and UnitedHealth, which can leverage AI for efficiency, while warning that firms relying on continuous AI breakthroughs face significant risks if the AI hype bubble bursts.
