i'm really not corcerned but i was just curious about whether or not carbon had similiar issues in cycling, the problem they've run into with boats is wanting them lighter and lighter sot ey underbuild structures that need to bebulked up, they could get away with this to a degree with fiberglass since fiber glass will flex a bit, carbon on the other hand will just crack and in some cases fail catastrophically so it sounds like cycling ran into similiar issues with carbon structures failing big time.
