Where it should end is with humans creating engineered (whether genetic-engineered, or using fungi, etc. is irrelevant) foods and materials such that we don't need to be farming, brutalizing, and killing animals and plants on industrial scales, deforesting vast regions to graze cattle, etc.. We are likely generations away from that, but it does seem to be the direction we're headed.
