‘We could hit a wall’: why trillions of dollars of risk is no guarantee of AI reward

Progress of artificial general intelligence could stall, which may lead to a financial crash, says Yoshua Bengio, one of the godfathers' of modern AI

Will the race to artificial general intelligence (AGI) lead us to a land of financial plenty - or will it end in a 2008-style bust? Trillions of dollars rest on the answer.

The figures are staggering: an estimated $2.9tn (2.2tn) being spent on datacentres, the central nervous systems of AI tools; the more than $4tn stock market capitalisation of Nvidia, the company that makes the chips powering cutting-edge AI systems; and the $100m signing-on bonuses offered by Mark Zuckerberg's Meta to top engineers at OpenAI, the company behind ChatGPT.
