A warning about working with damaged carbon fiber frames: I heard a discussion on NPR a year or two back, apparently carbon fibers are very similar to asbestos fibers and likely pose some of the same health risks. There are several articles online, here is one I found on Google: http://www.newscientist.com/article/dn13946-nanotubes-toxic-effects-similar-to-asbestos.html

Needless to say, I wouldn't recommend ever trying to fix a damaged carbon frame. The fibers are safe when sealed in plastic but once the frame is cracked, broken or maybe even just chipped it probably shouldn't even be handled except with a pair of gloves (and maybe a dust mask or respirator) and only then to dispose of it or possibly to take it to a proper recycling facility. (you can't just drop it in your curbside recycling bin, and I couldn't tell from the article but Trek may not even be able to recycle frames from other manufacturers, and at this point it doesn't even look like they are even recycling anything besides waste from their own production/testing facilities.)

Will anyone ever really improve on the classic steel frame? Seems doubtful sometimes..., but there is bamboo.

Carbon fiber is definitely recyclable! Take a look:
