There is a lot of design and UX and market exploration to do around learning systems. The way that a user will consume the outputs of a learning system are far from well defined right now. Larger companies have an advantage in many ways (like Google Now can exploit google's reach into android home screens) but consider a tool that helps you garden, find a restaurant or dress yourself based on your preferences - what would that UI look like? Google doesn't have an answer to that, yet.
