And here lies the opportunity, Recommendation Engines that can balance between exploiting what they know about the user and exploring the unknown (i.e. enabling the discovery of new items and better learn the user).

E.g. you’re going on a date, you open up your favourite restaurant locator app – it takes your history and recommends something near-by you might like … somethings amiss – what if your date is a vegan. Theoretically (ignoring scaling for millions) it shouldn’t be too hard to extend our current recommendation engines to handle this.
