Several AI-powered robocalls hit my phone last month. They had voice-recognition software, thought it seemed programmed to get me to consent to speaking to a live operator. But I really resented them pretending to be human when they weren't. So I just asked it a question that a human could answer that an AI couldn't. (Something like "Did you watch the Super Bowl this year?")

Once I even stumped one who'd said its name was Ashley just by asking: "What's the first letter of your first name?"
