carbon fiber is so far one of the best materials for bikes.
there is no reason to be afraid of new technology. (carbon fiber is not new at all but still being improved)
even my grandma has a carbon fiber wheelchair, actually. :-)
Obvious that you have no issues with carbon fiber, otherwise you would not have bought this bike.
To me carbon fiber and folders do not play well together as folders (at least mine) get banged around quite a bit and that is what carbon fiber does not like too much. This has nothing to do with voting agains new technology but with understanding of materials and choosing the right one for a given purpose.
