Gym climbing has unquestionable value in terms of developing face climbing technique, as well as fitness and strength. But there is over 100 years of alpine climbing (i.e. – trad) history that was played out before the existence of indoor gyms. While starting one’s climbing apprenticeship in the gym is certainly one way to go, I’m not sure why anyone would be dogmatic about this approach. Safe rope management and belaying skills can be learned anywhere. If alpine climbing is at the heart of one’s interest, why not start by going straight to the mountains, and immediately shape the gym in your mind into what it really is- a place for physical training. The gym otherwise conditions your mind in a number of ways, some of which may require “unlearning” when you shift to the mountains. Gym climbing and sport climbing focus almost solely on the technical difficulties and mechanics of climbing; these are important aspects of climbing but they are often secondary in alpine climbing. Among other things, gym climbing does little to develop situational awareness.
This shouldn’t come as a surprise. The old school approach of yesterday was that the older climbers would mentor the younger climbers, and the knowledge of the mountains was passed down from one generation to the next; that style is largely vanishing. The trend in climbing over the past few decades has been towards individualism- teach yourself, then (maybe) teach others. The advent of commercialism in guided expeditions has further helped to stigmatize the idea of hiring a guide to learn the ropes, and the proliferation of detailed guidebooks removes some of the mystery that otherwise would prompt a greater level of preparedness, while leaving all of the hazards; ego and ambition, while certainly not new to climbing, have become all too prominent tools for measuring one’s readiness for the next challenge. The “apprenticeship” in alpine climbing if it exists has to an extent become a function of surviving these forces and, hopefully, a delayed development of humility and respect for the mountains and a more realistic assessment of one’s strengths and weaknesses. All of this gives potential for a more dangerous learning curve, as well as creating an armada of self-taught “instructors” who probably don’t even realize they are teaching unsafe methods.
I don't mean to overgeneralize as there are plenty of exceptions to the above, nor do I intend to convey cynicism. The above trends just tend to speak louder when they are observed in practice.
I think if you don’t take someone’s ignorance personally, then the attitude you convey will be of genuine concern and respect, and they will listen to what you have to say.
