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.
Did you think about this before you wrote it?
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.
How is it obvious?
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.
Wow. Equally confident, equally confused.
The brain processes the information from the nerves.
Might just be that nerve cells by themselves "experience" something when stimulated, but pain perhaps requires certain structures of neurons or even parts of a brain to be interpreted as "pain". I'm just spitballing though since I'm not a neuroscientist or anything like that.
Physical pain only exists from nerves. Brains don't have any nerves. No nerves. No pain.
