Amazon and Google's virtual, voice-only assistants both allow you to carry out simple tasks. Asking questions like "who is Barack Obama?" or "how many cups are in a quart?" will offer up variations of the same answer. You can ask it to provide all sorts of information – the results of mathematic equations, the weather, or the latest headlines informed by your personal news settings. Every question you've asked can be revisited in the Google Home or Amazon Alexa app, even allowing you to play audio of your query so you can hear how the device hears you. These responses are stored in the cloud, which, depending on how paranoid you are, is unnerving. Equally unsettling: you're actually handing over money to Google (or Amazon) to have an always-listening microphone in your home. So there's that.
