> Design is complicated and very much like taste - subjective. The problem is "Design" is a bit like UX/UI ,it doesnt really mean anything concrete,but some vague thought process to create a product. Usability is not subjective,that's why I prefer that word. Usability is a hard science,there are rules,just like in programming. You want a product to be smart,to facilitate whatever your user is trying to do,to make simple what might sound complex,but you also want to get user's feeback because they'll always try to use your app in unexpected ways. I think that field could benificiate from all these machine learning experts.Imagine apps that really adapt to their users,trying to learn patterns,adapting the UI depending on usage etc ... I'm not aware of the researches in that field,but it could be the next big thing in usability.
