Let me make this point dreadfully clear, though: Your family members do not need an Amazon Echo or a Google Home or an Apple HomePod or whatever that one smart speaker that uses Cortana is called. And you don’t either. You only want one because every single gadget-slinger on the planet is marketing them to you as an all-new, life-changing device that could turn your kitchen into a futuristic voice-controlled paradise. You probably think that having an always-on microphone in your home is fine, and furthermore, tech companies only record and store snippets of your most intimate conversations. No big deal, you tell yourself.

Actually, it is a big deal. The newfound privacy conundrum presented by installing a device that can literally listen to everything you’re saying represents a chilling new development in the age of internet-connected things. By buying a smart speaker, you’re effectively paying money to let a huge tech company surveil you. And I don’t mean to sound overly cynical about this, either. Amazon, Google, Apple, and others say that their devices aren’t spying on unsuspecting families. The only problem is that these gadgets are both hackable and prone to bugs.

Before getting into the truly scary stuff, though, let’s talk a little bit about utility. Any internet-connected thing that you bring into your home should make your life easier. Philips Hue bulbs, for instance, let you dim the lights in an app. Easy! A Nest thermostat learns your habits so you don’t have to turn up the heat as often. Cool! An Amazon Echo or a Google Home, well, they talk to you, and if you’re lucky, you might be able to figure out how to talk back in the right way and do random things around the house. Huh?

A good and concise explanation of why these useless devices are something to be very afraid of.
