Sentience will not be obtained by digital AI, re: Godel and Penrose. However, a sophisticated homunculi can be made, which derives its patterning on extant human generated data, which is what we currently have. Until we introduce unconstrained analog components... not possible.

Second, Oppenheimer said on his deathbed (to paraphrase) "The only way to prevent us destroying the world is to NOT try to stop it." He knew human nature. This is why crypto is so effective.. it isn't constrained. I think we need to fight constraints with every fiber in our being so we can emerge on the other side with a healthy world.
