I could still please humans fine, just in ways that actually have more thought to it than a biological mechanism we evolved to have merely to continue the species.
You say that like the simple things aren't worth it because they're simple.
Worth has nothing to do with complexity. People only fuck because hormones dictate it.
Now we only do anything because of our brain chemistry, but at least in making a piece of music or inventing something there is a level of conscious thought and creativity that in my eyes makes it worth while and lasting. For all the hyperbole and hysteria, you might as well be rubbing elbows than fucking in every sense other than how the chemicals can make you feel and desire.
People will put up with horrible character flaws that they wouldn't take in a "friend" but throw in nebulous feelings of love and an inherited sense of meaning and people do and say all kinds of things that they are only doing because of a chemical feeling that they are largely unaware of and most often fail to separate from conscious thought and abstract concepts.
With the right cocktail of chemicals I can be "in love" with an apple, I can want to fuck a tire iron, I can see beauty in a pile of shit.
Now until more is learned about the nature of consciousness and qualia, I can't say for certain that there is any more value in a book or a conversation than an hours fucking, but it certainly seems that way, especially since we imitate so much of the automaton behavior of our animal ancestors in this respect.
