Hey! So I feel a lot of creativity is 'combinatorial', i.e knows what two things might go well together. Artbreeder kind of gamifies that by making it very easy. So many images may look similar but some people can really develop their own style with time.
Also, often my favorite part of artbreeder is when artists take what they save as the inspiration or building blocks for full works. It's really an inspiration tool, but saying inspiration-breeder is a mouthful.
More generally, I think computation can meaningfully augment human creativity by providing surprise and break us out of our loops.
Best, Joel
