Marc Andreessen, co-founder of Netscape, is one of the biggest investors in technology. In an interview with The Telegraph, he spoke about how he envisions the future of computing. It's essentially an extension on the idea of the "Internet of Things." He thinks mobile phones will begin to be replaced in just 10 years. "The idea that we have a single piece of glowing display is too limiting. By then, every table, every wall, every surface will have a screen or can project." Within 20 years, he expects most new physical objects to have some sort of chip implanted within them. "The end state is fairly obvious — every light, every doorknob will be connected to the internet." The term for this is "ambient computing." There will obviously be a transition period — perhaps the so-called internet of things is just an early phase of that transition. But with powerful chips and sensors becoming incredibly cheap, Andreessen's scenario seems possible. I guess it's time to get cracking on those security and privacy concerns.
