A good share of notable cathedrals have burned in recent history, and some of them have been rebuilt using modern techniques (e.g. Chartres, one of the most notable french cathedrals now has a metallic structure to bear its roof). These new techniques are both elegant and a better fit, as they protect the building from a (likely) fire in the future.

Arguing that cathedrals' wooden roofs are built to last while we don't know how to build longer-lasting work is a very curious take on the situation.
