This is written from the perspective of a cynical person. I believe we are supposed to take this person to be wrong about "everything" and "everyone" in the sense that logically it is impossible for these absolutes to exist. But, I think the person represents a large segment of the youthful population and how they see the world. In a world where tragedy is apparent, and knowledge is deep, it is easy to become disillusioned and feel isolated. As a cynical person, the person is aware of the aspects of culture he adopts from certain groups, and then he rejects them when he sees others acting the same way because he realizes it is all a charade. He wants to "keep changing" to prove he isn't vulnerable to the attacks on his independence made by his society's norms and views on culture. This might be far too deep an idea for just some rock band (I don't know whether or not the band is intelligent), but the ending lines emphasize everyone gets old and everyone is dumb, which would include the speaker. The irony is thus that while speaker is aware of the flaws of everyone, he spends all his time trying to avoid these flaws, when the flaws will inevitably touch him assuming they haven't already because by isolating himself he learns nothing and simply will become old and dumb.
