For six years, the Google company focused on artificial intelligence. Several steps were taken until last February when his experimental conversation tool called Bard was shown to a group of users.

“Bard tries to combine the broad knowledge of the world with the power, intelligence and creativity of our great linguistic models. It draws on information from the internet to provide fresh and high-quality answers,” the company explained at the time.

However, last Sunday, in an interview with CBS, Google CEO Sundar Pichai revealed that he doesn’t know how it works. This after discovering that he had learned a language, Bengali, with no prior training and only by receiving assignments in it.

In addition, it was recorded with concern that Bard wrote an essay citing five books, which did not exist, to solve an economic problem.

“There is an aspect to this that we (…) call a ‘black box’. You know, you don’t quite understand… And you can’t say why he said this, or why he was wrong. We have some ideas and our ability to understand them improves over time. But that’s where the situation is,” Pichai said.

The astonished interviewer asked him that despite not fully understanding it, he released it to the society. “Yeah. Let me put it this way. I don’t think we fully understand how the human mind works either.”

In the conversation, the CEO said that they were responsible for not launching advanced models as society has to get used to this kind of technology as the company tries to generate more layers of security. He also assured that they “have the urgency to work and implement it in a favorable way, but at the same time it can be very harmful if implemented incorrectly.”
