Is it possible that, rather than things becoming physically hard-wired into us, our ability to communicate and work together has gradually streamlined the learning process? Of course it stands to reason that we would physically change to adapt to our changing environments, and maybe a NN would be able to adapt at a greater rate.
The network has grown so rapidly recently that there is no hope of getting reward unless you have a purpose built farming rig, and that’s really devastating to the block chains longevity. The most compelling part about this crypto to me is that it could be farmed by anyone with their extra HDD/SSD space, but if there is no reward for the performance hit then the coin is much less interesting to the general public, who you need most for long-term acceptance of Chia.
