OpenAI:s styrelseordförande Bret Taylor anser att vi nu befinner oss i en AI-bubbla. Det säger han i en intervju med The Verge. Taylor, som även är vd för AI-agentstartupen Sierra, sällar sig därmed till OpenAI:s vd Sam Altman, som även han uppgett att det råder en AI-bubbla. Vad Altman uppgav var att "någon kommer att förlora enorma summor pengar på AI". Samtidigt är inte Taylor särskilt orolig över situationen. "Jag tror att det är sant att AI kommer att förändra ekonomin, och jag tror att det, precis som internet, kommer att skapa enorma ekonomiska värden i framtiden. Jag tror också att vi befinner oss i en bubbla och att många människor kommer att förlora mycket pengar. Jag tror att båda dessa saker är helt sanna samtidigt, och det finns många historiska exempel på att båda dessa saker har varit sanna samtidigt", säger han.
