    Is this legit? This is the first time I’ve heard of human neurons used for such a purpose. Kind of surprised that’s legal. Instinctively, I feel like a “human brain organoid” is close enough to a human that you cannot wave away the potential for consciousness so easily. At what point does something like this deserve human rights?

    I notice that the paper is published in Frontiers, the same journal that let the notorious AI-generated giant-rat-testicles image get published. They are not highly regarded in general.

      They don’t really go into the size of the organoid, but it’s extremely doubtful that it’s large and complex enough to get anywhere close to consciousness.

      There’s also no guarantee that a lump of brain tissue could ever achieve consciousness, especially if the architecture is drastically different from an actual brain.

        Well, we haven’t solved the hard problem of consciousness, so we don’t know if size of brain or similarity to human brain are factors for developing consciousness. But perhaps a more important question is, if it did develop consciousness, how much pain would it experience?

          Physical pain? Zero.

          Now emotional pain? I’m not sure it would even be able to accomplish emotional pain. So much of our emotions are intertwined with chemical balances and releases. If a brain achieved consciousness, but had none of these chemicals at all…I don’t know that’d even work.

              Didn’t have to. Kind of an obvious thing to point out, but OP didn’t specify what type of pain he meant, so I figured I would, just in case.

                  Human brains don’t actually have any pain receptors (even though headaches would have you seriously believe otherwise), so a brain alone wouldn’t be able to feel pain any more than it would be able to smell or see.

    Some cells get taken from you and turned into stem cells.

    These are converted into brain cells, and nerve cells, on a chip that represents the scaffolding, interface, and connectivity.

    Then the whole ‘organ-device’ gets surgically installed into your brain, and through gene therapy, the brain cells grow into, connect with and network into your existing tissue.
