Has the EdTech revolution already happened?

It has become generally accepted that technology is going to revolutionize education, ELT included, in the near future. Moreover, it is seen as an incontrovertible fact by some (EdTech evangelists in Silicon Valley and New York, for example) that education is still stuck in the nineteenth century and that certain educational technologies under development will finally bring education into the twenty-first century, boosting learning efficacy by double-digit percentage points and change teachers’ jobs forever. ‘The revolution is coming’ we are told.
