The correct answer to this open question is the following.
Hedonists such as Epicurus and Mill have claimed that pleasure is the only thing worth pursuing its own sake. If some people would choose not to plug into the experience machine, does this show that hedonism is false?
No, what it means is that under the belief system and consideration of that individual, hedonism is not the way to receive pleasure and there would other activities or satisfactions that would report pleasure in doing them. Diversity in people's character and beliefs makes life more rich and interesting in that the search for pleasure has different ways, according to the satisfactoriness, values, and goals of each individual.
Although Hedonists such as Epicurus and Mill have claimed that pleasure is the only thing worth pursuing its own sake, other thinkers and philosophers considered that pleasure is the final result of getting accomplished that what made us thrive under different -and sometimes- difficult circumstances.
So pleasure, fr the sake of the pleasure it is not the only way to approach this.
