Buildings of the future might be constructed by swarms of robots

The following is an excerpt from Soonish by Kelly and Zach Weinersmith. Thanks to recent advances in robotics, computing, and other technologies, a small but growing number of scientists and engineers think robot-made housing might finally be possible. In fact, not only is it possible, it may be far better. Robotic construction may increase the speed of construction, improve its quality, and lower its price. There are a number of ways this could work, including giant gantries that behave something like 3D printers, and robotic arms on wheels that might directly replace construction workers.
