Maybe the idea of using real human braincells cultured, extracted or salvaged from humans is terrifying but if indeed more efficent, it could help guide us away from a potential dead we could be on at the moment. What I still find more terrifying is having something really more powerful than a human brain not in raw power but in general intelligence with all human subtleties and all. The idea is not terrifying by itself but the potential of a bad actor using this for nefarious ends.
