Wilderness Survival:
So many people barely know how to knap or make a fire, how the hell would this world work without power, google and the internet? Things would go to hell. We need to teach the boys to stop playing Call of Duty and eating chips and learn to make a fire and hunt. We need to teach the teenage girls(that dosent know already) that fashion isnt everything, and a dark age is an age of compromises, those too small jeans can be used for other things than failing at looking pretty, for example, feeding a fire or cutting into useful cloth for example for bandaging a wound. If we stay this way, the next generation will be a bunch of Apple consumer slaves that can barely screw a lightbulb in place!
I don't know about this part of your argument. There seems to be a little bit of bias at work here. These skills are probably not going to be needed by a great deal of people. The conditional that what if all the things we depend upon were to end tomorrow is also a little on the strange side. Why should we accept this anymore than the mandatory education of horror literature given the future condition that cosmic horrors will arrive tomorrow and people with the most love-craftian knowledge and the hardness of mind to brave the dangers will be the ones that prevail?
It seems to me that learning about these things are often not going to pay out in the end, contradicting the potential utilitarian argument why we should learn survivalist knowledge. It seems to me with arguments such as these that the next best option would be to educate people to seek out those that know how to do these things instead of every single individual themselves spending time learning these disciplines for events that may not come to pass.
To be clear, I'm not sure it's all that valuable teaching people obscure facts like what jazz is or intermediate chemistry. There is no question that our species have greatly benefited from the deep curiosity of our surroundings, and the intellectual achievements this has led to, but I think thinking less of someone just because they haven't grasped a piece of information someone else has isn't justified. What matters more I think, is whether they have enough knowledge and enough knowledge about methods of inquiry to more or less make competent choices in their lives. Some examples: I don't think an engineer, even given the importance of that discipline, is justified in making fun of someone just because they don't know how to build a stable building above a certain height, or a trained physicist to make fun of someone because they can't recite the leading theories that guide current subatomic investigations. There are a great deal of things that people don't need to know about to live a meaningful life.
Above all I think, is the theme of teaching people how to educate themselves, or to concede that they do not know the answer when they in fact don't. Far more important than educating people in certain disciplines, I think is to instill into them the logical means to sort which answers are good and which are not. Having the ability to know which arguments are sound and how to plan to acquire knowledge that one needs and doesn't have seems to have far more utilitarian value due to it being guaranteed that these factors will be used at one point or another.
