An artificial intelligence-powered chatbot created by New York City to help small business owners is under criticism for dispensing bizarre advice that misstates local policies and advises companies to violate the law.

But days after the issues were first reported last week by tech news outlet The Markup, the city has opted to leave the tool on its official government website. Mayor Eric Adams defended the decision this week even as he acknowledged the chatbot's answers were "wrong in some areas."

Google co-founders Larry Page and Sergey Brin loved pulling pranks, so much so they began rolling outlandish ideas every April Fools' Day not long after starting their company more than a quarter century ago. One year, Google posted a job opening for a Copernicus research center on the moon. Another year, the company said it planned to roll out a "scratch and sniff" feature on its search engine.

The jokes were so consistently over-the-top that people learned to laugh them off as another example of Google mischief. And that's why Page and Brin decided to unveil something no one would believe was possible 20 years ago on April Fools' Day.

Google has agreed to purge billions of records containing personal information collected from more than 136 million people in the U.S. surfing the internet through its Chrome web browser.

The massive housecleaning comes as part of a settlement in a lawsuit accusing the search giant of illegal surveillance.
