HoloLens supplements what you see with overlaid 3D images. It also uses artificial intelligence (AI) to generate relevant information depending on the situation the wearer is in. The information is then augmented to the your normal vision using virtual reality (VR).
It left a lot of us imagining its potential, from video games to medical sciences. But HoloLens might also give us insight into an idea that goes beyond conventional artificial intelligence: that technology could complement our intelligence, rather than replacing it, as is often the case when people talk about AI.
