I'm certain this topic has been addressed many times, but I can't see how to reconcile basic morality with "it's just a calculation". Tell me I should not inflict pain on sentient beings while subscribing to the belief that pain is simply one particular result of a massive mathematical calculation. It's literally just a number/matrix.
Perhaps you're not over-valuing pain, but under-valuing numbers. There's no reason to think that morality can't or shouldn't center around minimizing a pain metric. That would put it in line with any other trajectory-planning-under-constraints problem. Once you've done a bit of work in trajectory optimization, you start to feel the numbers come alive, and develop a visceral feeling for them. I wince when I see a car…
Maybe we're deeply wrong about our intuitions, and actually no conscious experience is happening in the brain at all, despite the brain having an incorrect model about itself which predicts this (and causes it to make utterances claiming that it has experiences). That's the school of thought known as eliminitivism. Under this view, all suffering is a myth, in the same way that luckiness and angels are.
