This article gives an introduction to the field of topological materials, aimed at other professional scientists. The main thesis is this: "We have theoretical understanding and many ideas for novel devices, but ongoing materials development suggests the tantalizing possibility of our being at the dawn of a topological age". One especially enjoyable part of the article is the end, where the authors give a quick survey of potential applications of (2+1)-dimensional materials in new-generation devices. In particular, the authors focus on Weyl/Dirac semimetals.
