People tend to like discussing the differences between art and design, and point out that art serves no function while design does. I don’t know about that, but I would rather live in a world surrounded by art than surrounded by apps and ads.

On this subject, I like to think that Design mainly serves to solve a problem, even if this problem is simply "aesthetic", to make a more beautiful object. Since art is not intended to solve a problem, it can even say about a problem, but hardly by itself will solve a problem.
