IoT promises to make our environment, homes, offices and vehicles smarter, more measurable and more talkative. Amazon's smart speakers, such as Echo and Google Home, make it easy to play music, set timers or retrieve information. Home security systems make it easy to monitor what's going on inside and outside, or to see visitors and talk to them. Meanwhile, smart thermostats can help us heat our homes before we go back, and smart bulbs can make it look like we're at home, even when we're decking out.
Looking beyond the home, sensors can help us understand how noisy or dirty our environment can be. Self-driving cars and smart cities can change the way we build and manage our public spaces.
However, many of these innovations can have significant impacts on our privacy.
