A hunter/gatherer society could never support a population of our size. So really, the only way for your ideas to be realistic or credible is to kill off a good chunk of Earth's population. Is this what you're proposing? Otherwise, what is the use in dwelling on past forms of society that only led us to where we are today? I would say we are more interesting than any of the things you mentioned simply because we have the capacity to discuss what is the most interesting. Evolution did not end with us by any means, it is ongoing. It would be pretty impressive if we as a species lasted a few billion years. All of the advancements that you are opposed to have only ever served to aid our advancement as a species, so if you find that so fascinating to imagine, why are you so against it?
