Ariel Bleicher writes on the future of wearables: “Over time, … machines will learn to anticipate your actions and emotions and will automatically tailor your environment to suit your needs — muting your alerts when you’re in an important meeting, dimming the lights when you drift off to sleep. They may even recognize subtle cues you don’t notice or can’t sense, such as early signs of depression or the onset of a migraine. And when our computers know us better than we know ourselves, they will help us to communicate better with one another. They will monitor our conversations and inform us when others are bored, inspired, hurt, grateful, or just not on the same page. They will encourage us to speak up when we are shy, stop us from sending e-mails when we are angry, and remind us of what makes us happier when we are sad.”
