...PSHTF also. It's surprising, sometimes, about who regards themselves as a survivalist/prepper/what-have-you. There are plenty of your stereotypical types, but every-so-often some big name will announce that they're worried about TEOTWAWKI, get a lot of publicity... Usually along the lines of "Have they lost their final marble" in tabloids, but... Of course, occasionally, there are those whose statements are in-line with their particular area of expertise - the number of well-respected economists currently going "heads-down, take cover" is well above background levels.
Of course, it does make me wonder how many of these are planning to not survive, or just have them and their immediate family survive... Philanthropy goes a short way... On the other hand, do you have to help someone who refuses to help themselves? Or, at least, refuses to try to help themselves?
I also wonder how many of these people actually prepare for afterward? Stored food lasts only so long; the best way to store seed is to have some of it growing as crops, storing some, replanting some, rotating the old seed stock out. How many have a small library of books on a reasonably wide range of subjects, technical and scientific. And some art books - I am not so much of a philistine that I do not see value in art for improving the human condition.
There are many ways the world could end, or at least receive its catalyst... A large solar storm hit the Earth a few days ago, fortunately not large enough to cause damage to our electronic society, but what would happen if one was? I know that a large amount of my work-space would be useless - so many electronics parts made useless (possibly)...
But we still prepare, we still try to not provide too much publicity to what we do.
Game theory, really... If lots of people took prepping seriously, it wouldn't be a problem to let everyone know that we did - however, because everyone doesn't announce their plans, it's better that no-one does. Of course, that assumes everyone is rational, and that they are no people who'd try to take advantage of the situation... then again, game theory does allow for that.
I got ordained a few weeks ago. Not that I'm religious, or anything other than an atheist - it's very handy to have by the side... I need to find a few people, create a religious order based around accruing prepping and keeping knowledge alive.
I've also managed to order a copy of a book that I've known of for well over a decade and a half - I only need the one chapter, but it's worth having the rest of it as well. The book is on catalytic chemistry (I wrote that I like to accumulate knowledge) - the particular chapter of interest involves how to create a zeolite (a particular family of crystal) that will convert ethanol (drinking alcohol) to heptane and octane (aka petrol, gasoline)... Of course, obtaining the raw materials to create this may be difficult PSTHF, which means stockpiling, finding in-ground mineral sources, or chemically making the precursors out of rawer materials.
The problem is that most of our technology involves a very long manufacturing chain... Maybe have the religious order also try to improve some of the manufacturing chain problem. Which gets back to funding - while this world exists, it's difficult to tear oneself away - you need to render unto Caesar that which is Caesar's, which doesn't give you much time to do all the other things that need to get done...
