You forget that some people like general purpose computing. Android and other mobile operating systems (as well as Chrome OS) do have great security, but that comes at the expense of functionality (arbitrary code execution is discouraged, putting things inside apps and strict APIs make scripting and tinkering infeasible) and user control. One of the mentioned in the talk was being able to use the traditional Linux stack and being able to use your smartphone as a general purpose computer (2:22, 4:12). I hope one day there's a solution, but it seems trade offs have to be made to have one or the other.
