Should we fear an artificial intelligence bubble bust?
Recent swings in tech stocks are reviving fears of an AI bubble — and some experts warn that if it pops, the fallout could be bigger than anything Wall Street has ever seen.
"There are many indications that we are in a bubble," said Itay Goldstein, a finance professor at the University of Pennsylvania's Wharton School.
"It seems likely that there is overpricing," he added.
The numbers back him up. The five biggest companies on Wall Street — all tech giants — are worth a combined $18 trillion, almost the size of China's entire economy.
