Rockfall, lightning strikes, decomposing granites, etc. are all waiting to pounce on even the most experienced climbers.
That is true that there are inherent dangers, just like driving to work or flying on an airplane. I was a senior climbing instructor with Colorado Mountain Club and also have been climbing all over the world on major peaks. The crazy things I have seen people do while climbing outnumber the crazy things I have seen people do when driving. Nothing is perfectly safe, but it is best not to be one of the careless that is just asking for an accident.
