No one knows how Google Duplex will work with eavesdropping laws

In Google’s demonstration of its new AI assistant Duplex this week, the voice assistant calls a hair salon to book an appointment, carrying on a human-seeming conversation, with the receptionist at the other end seemingly unaware that she is speaking to an AI. Robots don’t literally have ears, and in order to “hear” and analyze the audio coming from the other end, the conversation is being recorded. But about a dozen states — including California — require everyone in the phone call to consent before a recording can be made.
