Now what makes good design is one of the biggest questions and one of the hardest questions to answer. Sometimes people asks us, because how do you decide to put an object in the collection of MoMA, because you know it is a small collection it is not huge. It is about 4000 objects.

You can talk about anything you want, form function, all of these different equations that have been given the world as possible definitions, but the truth is this. It is a very complex recipe. The world has become more complex and you cannot anymore have an equation with just two variables. This is like, you know, differential equation but many variables.

When I can tell you, is one of the litmus test is. Think if this object were not on earth. Would be a pity? Would you miss it? I tell you that is really interesting because it really helps. Sometimes objects are not immediately functional, they are not to be set upon or to be used to eat or to be used to turn on the volume. Sometimes objects just deliver emotions or are just part of your life that is also enough.

The moment an object seems necessary then you can move to judge if it is beautiful, if it works well, if it is waste energy, those are all considerations. But the idea of necessity or good addition to the world really usually works.
