I feel that CSS in JS is real future. They already allow to create truly dynamic applications, with theming and on-the-fly styles changes. I know that you can do that without it, just applying different classes, but now they are truly first-class citizents, without any constraints.
So I definitely recommend everyone to take a look at them (I guess, styled-components for react is the best library out there, but not sure about other frameworks).
