Well, one hint is that if you look at the actual real intelligences (aka people), not that many express a desire to go directly to wireheading without passing Go and collecting $200...
I think that is in large part due to signalling and social mores. Once people actually do get the ability to wirehead, in a way that does not kill or debilitate them soon afterwards, I expect that very many many people will choose to wirehead. This is similar to e.g. people professing they don't want to live forever.
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
