Convergence is "enough", so to say. It means "striving" for something, you know you can't achieve ("as a whole" at least). (a mathematical concept, fyi)

Words like "perfection" et simile are "non"-words in my mind-castles.

And of course it is easier to shoot the messenger that "tries" to give you a gold-nugget (which you don't expect to be a gold-nugget, because it is for him at first and at least: You at first just don't know what it actually is... for Chipit e.g. every nugget is a pile of shit, surely) than at least "trying" to let his "message" grow into your core. I get it. KISS-principle again.

The "contradiction" or "cognitive dissonance" in this typical aspect of human communication is:

Dialogue always connects sme with his message. We barely can divert the people we communicate with from the messages they send to us. It is just human.

That is why i think e.g. : Chipit is an asshat. So to say. I'm a human being, so this even is easy to understand.
