>> Where are the startups trying to keep you addicted to the internet in a way that improves your life? > consider the gamifying elements of Khan Academy, Duolingo and other e-learning sites for example It's worth noting that I've heard a lot of criticism of e.g. Khan Academy from certain components of the mathematics education community. Concretely, they feel that the material there is designed to increase engagement and provide a sense of accomplishment ASAP, and that the learning processes that fit those goals are detrimental to development certain mathematical skill sets. I.e. you might learn how to compute derivatives really well, but at the expense of really understanding limits or the fundamental theorem. Mind you, mathematics educators have always been an internally divisive bunch, so take from it what you will.
