The pleasure machine argument is flawed for a number of reasons:
1) It assumes that, despite having never been inside the pleasure machine, but having lots of experience of the world outside of it, you could make an unbiased decision about whether to enter the pleasure machine or not. It’s like asking someone if he would move all his money from a bank he knows a lot about to a bank he knows basically nothing about and that is merely claimed to make him richer than his current bank. I’m sure that if someone would build a machine that, after I stepped into it, actually made me continually very, very much happier than I’ve ever been, it would have the same effect on me as very heavy paradise drugs have on people: I would absolutely want to stay inside the machine for as long as I could. For eternity, if possible. I’m not saying it would be a wise decision to step into the pleasure machine, (see point 2, 3 and 4 below), but after having stepped into it, I would probably want to stay there for as long as I could. Just as this choice might be considered biased because my experience of the pleasure machine can be said to have made me “unhealthily addicted” to the machine, you are just as biased in the other direction if you have never been inside of it. It seems most people have only a very vague idea about how wonderful it would actually feel to be continually super happy, and this makes them draw unfair conclusions when faced with the pleasure machine argument.
2) We know that “pleasure machines” either don’t yet exist at all, or, if they exist, have so far always seemed to come with too high a prize in the long run (for example, we are told that drugs tend to create more pain than pleasure in the long run). This makes us spontaneously tend to feel sceptical about the whole idea that the pleasure machine suggested in the thought experiment would actually give its user a net pleasure increase in the long run. This skepticism may never reach our conscious mind, it may stay in our subconscious, but nevertheless it affects our attitude toward the concept of a “pleasure machine”. The concept of a pleasure machine that actually increases pleasure in the long run is a concept that never gets a fair chance to convince us on its own merits before we subconsciously dismiss it because we know that if someone claimed to have built such a machine in the real world, it would most likely be a false claim.
3) Extreme happiness tends to make us lose control of our actions. Giving up control of our actions usually decreases our chances to maximize our pleasure in the long run, so this further contributes to make the pleasure machine argument unfair.
4) If all human beings stepped into pleasure machines and never got out of them, there would be no more development (by humans): If instead some or all humans continue to further the tech development and further expand in universe, it will be possible to build even better pleasure machines later on, than the pleasure machine in the thought experiment. There will always be a trade-off between “cashing in” (by using some time and other resources to build and stay in “pleasure machines”) and postponing pleasure for the sake of tech development and expansion in order to make possible even greater future pleasure. The most pleasure-maximizing such trade-off may very well be one that doesn’t include any long stays in pleasure machines for the nearest 100 years or so. (At some point, we should “cash in” and enjoy huge amounts of pleasure at the expense of further tech development and expansion in universum, but that point may be in a very distant future.)
