Smart speakers are so 2017. This year saw the rise of the smart display, with Google opening up its Home platform to third-party manufacturers like JBL and Lenovo, and Amazon putting out a much-improved version of its Echo Show. Smart displays add a lot of functionality to virtual assistants, facilitating video calls, step-by-step recipes, weather updates, and entertainment. Filling your house with microphones and cameras can also be a little creepy, something device makers seem to have realized as they've also added privacy functions, or in the case of the Google Home Hub, done away with the camera altogether.
