I don't consider morality to be a terminal value.
That implies that you would do anything at all (baby-mulching machines, nuke the world, etc.) for sufficient stimulation of your pleasure center.
Well, the pleasure center and the reward center are different things, but I take your meaning. I think that I could be conditioned to build a baby-mulching machine or a doomsday device. Why not? Other people have done it. Why would I assume that I'm that different from them?
EDIT TO ADD: Even if I have a value that I can't escape currently (like not killing people), that's not to say that if I had the ability to physically modify the parts of my brain that held my values I wouldn't do it for some reason.
Part 1 was previously posted and it seemed that people likd it, so I figured that I should post part 2 - http://waitbutwhy.com/2015/01/artificial-intelligence-revolution-2.html
