i do believe we must evolve beyond our human bodies to survive. as well as maintain a more continuous individual database of information and understanding to build consciousness upon. basically, how can we make that which stores our perceptions and information more durable and long-lasting so we can increase and expand our data-collecting abilities to create larger and more dimensional networks of understanding?
each time you die, your database gets wiped and at birth you have to rebuild, though some people are better at recovering data than others. but overall, as biological organisms, we are inefficient.
i believe that even if ai achieves becoming more human than human, it will not be a threat to humanness itself but an evolution–both our collective and individual consciousness will migrate into the structures that house ai. or perhaps ai will manifest in a manner which does not require a tangible structure.
