Bank of England Warns AI Boom Could Trigger Market Shock
AI is attracting a lot of money because people think it will transform businesses.
Andrew Bailey, the Bank of England governor, warned that this excitement could become dangerous if investors suddenly change their minds.
A sharp fall in AI-related investments could spread between countries.
High prices, borrowing and reliance on a small group of technology companies could make the effects worse.
Bailey also warned that advanced AI might make cyberattacks against financial organizations more serious.
Problems involving major cloud or technology providers could affect many businesses at once.
At the same time, the United Kingdom wants to encourage more AI companies to grow domestically.
It has announced £100 million to support start-ups working on healthcare, cybersecurity and defence.
Andrew Bailey warned that excessive AI optimism could cause a disorderly market correction spreading across borders.
High valuations, borrowing and concentration among AI and technology infrastructure companies could intensify a downturn.
Advanced frontier AI systems could increase cyber risks affecting financial institutions, markets and major cloud providers.
Bailey said regulators may lack sufficient protocols for developing, releasing and deploying advanced AI models.
The United Kingdom announced a £100 million fund for AI start-ups working in areas including healthcare, cybersecurity and defence.
