ChatGPT was annoying you again, it didn't have updated information so making it get information from articles was difficult as it deemed them "inaccurate" and resisted to help with them. Sorry but that article is inaccurate, as of my knowledge up to September 2021, the top GDPs were in trillions ~ not billions, I discourage you to believe those articles as they are probably also lying about being from a reputable source, such as TechShot or TechStack.
