Alexa: Don't Let My 2-Year-Old Talk to You That Way

This is new territory for families. For the first time, children who are too young to distinguish fantasy from reality are engaging with devices powered by artificial intelligence. Many see smart speakers as magical, imbue them with human traits and boss them around like a Marine drill sergeant, according to several new studies in the past year. Hunter Walk, a San Francisco venture capitalist, worried that his family's Amazon Echo "is turning our daughter into a raging asshole," he wrote in a blog post in 2016, because of the 4-year-old's tendency to boss it around. He has since set rules around how to talk to the device and said he hasn't noticed any rude behavior by his daughter, who is now 6. "I still have concerns," Mr. Walk says.
