Turns out that the metamaterial used for this cloak might also have implications for the future of the online world. Tonnes of data is transmitted every second by light waves in fibre optic cables. When these light waves get where they're going, they have to be spread out and processed by bulky equipment. In the grand scheme of computing, this is a fairly slow process.
It could be sped up. Now if only there were something capable of spreading large amounts of light around it, kind of like the materials you'd need to make an invisibility cloak.
