Every startup talks about changing the world, but most aren’t talking about the world itself or physical things in it. Most simply want to swap data packets and place entries in databases -- potentially important bags of bits, but bags of bits nonetheless. The world, though, is made up of atoms.
The barrier between bits and atoms is disappearing, with programmers no longer confined to the virtual realm, in part thanks to the Internet of things becoming more real. Now we can do more than write ones and zeros to a disk: We can actually write code that tells a machine how to extrude, cut, bend, or morph atoms. Now our software can turn on lights, change the look of a room, steer a car, move a wall, or more.
