Carbon really isn’t expensive. Aside from potential sun damage, that stuff will last a LONG time and take some serious punishment. If you are afraid of carbon fiber, you are done flying, since most new design planes are composite as well as well as driveshafts in hyper cars.
The reputation mostly comes from the fact that it won’t bend the way metal will (high elastic, low plastic deformation), and is unlikely to simply crack. When it goes, it GOES big.
Carbon bikes are absolutely repairable, though the guy’s at the shop in the business of selling bikes, not repairing frames may tell you different.

All true. I wouldnt repair carbon though, its just not worth it. I DIY all kinds of things, but not that. I looked it up and almost did it. In the end, as you mention, its not as if its expensive. When you pair that with the mode of failure (catastrophic), its simply too dangerous. I've ridden aluminum bikes after mishaps that bent tubes, etc....never mattered, but carbon just blows up.
I still use aluminum bars and a carbon wrapped aluminum stem (big fat pro stem). Makes me feel better from an integrity standpoint and theres no loss in weight, performance, etc...
