 When they first appeared, computers were as big as a room. A few years later, you could easily fit one on a desk, then your lap, and now, your hand, or even wear it. In the future, you'll put them directly under your skin. The first implantable mobile phone is expected to be sold by 2023. How will this affect the way we live our lives, communicate with one another, and absorb information? Until now, our online presence has been a projection of ourselves, with implants, real-time data from our physical bodies will become part of our digital footprint, redefining the meaning of being online and blurring the boundaries between the physical and digital world. Implantable and wearable devices will create great opportunities, but also great challenges for humanity. They will help monitor our health, provide immediate information about what we see, or help find missing children. Controlling devices with our brains will enable disabled people to fully engage with the world and open endless possibilities for teaching, learning, and many new experiences. They will also create an unprecedented need to define clear boundaries for personal privacy and risk-causing addiction, escapism and trauma. In the future, will it be possible to ever be offline anymore? And what will being online really mean?
