You are describing evolution without an utility function. That won't work. We may be able to come up with an alternative utility function but, given past history, I'm afraid we won't and will be aimlessly exploring the solution space.

A good parallel can be draw to evolution in painting. Up until the invention of photography, painting evolved to be photo-realistic. It made amazing strides, with breathtaking results. Once photography made that evolution path obsolete, painting struggled to find a new utility function. Out of that struggle, we got amazing outcomes in conveying feelings, a new utility function. Work in the first half of the XX century, from the likes of Munch, Dali, Picasso, optimized this function up to its limits. From then on? Painting is somewhat lost in the solution space without an utility function.
