Will man ever run out of ideas for entertainment?

I realize it's an odd question, and unfortunately, this is sometimes how my mind works. I think of rather morose concepts and dwell on them. However, this one's been bugging me for quite a while; I figured it may as well be a decent idea for discussion (hell, a good number of you have probably thought the same thing already):

Will mankind ever experience an absence of potential for creation in the world of entertainment? Will every song soon be composed? Will every script be written? If so, when would you guess these to occur?

 Note:

Half of me didn't want to post this, as I don't know if this will cause others to dwell on it like I do. The last thing I want to do is make people depressed.

[color="#cc8899"]Meh, I am already vastly disappointed in humanity, can't do much to me. Anyways, here's my take -
By the time this would happen, one or more of several other things will have happened

1. Mankind as we know it is destroyed, lost, or forgotten, allowing old ideas to be thought of as new and creative
2. A suppresive regime will limit free-thinking or dispose of creative materials and past entertainment media, again allowing mankind to re-imagine it believing it to be "new." In fact, the suppresive regime isn't even necessary for this - evidenced by the character archetypes common amongst all/nearly all cultures.
3. Mankind will utterly wipe itself out through war or scientific mistake, or be destroyed by a different existence (God, spacemen, molemen, etc). At which point this is moot. Anyways, never underestimate the creative potential of mankind - it takes direct intervention to stop imagination and creativity, evidenced by little kids creating imaginary friends when they are bored, playing pretend, seeing monsters in their closets.[/COLOR]
