Carbon bikes are made from hollow tubes, hollow tubes can buckle / collapse, plus carbon bikes are designed for lightness, not sturdiness. Wood can take a beating, but is a lot heavier.
The wooden bikes mentioned are made from hollow tubes too. "Materia Bikes frames are hollow and lightweight"
Hollowness is nonsensical argument. Hollow tubes maximize strength per weight
Carbon bikes are made for stiffness and ride quality - you can make equally light bikes with Alu / Ti.
