Recently I was wandering if there is someone or some group preserving , collecting , organizing and publishing all the knowledge of mankind ever created throughout its existence so that if ever mankind faces the 6th mass extinction we don’t have to reinvent the wheel and can have a kick start to our new post apocalyptic civilization .
Wikipedia is absolutely not useless without the sources. I don’t even know what to say, that statement is so deranged.
WP as it is is of course not useless. But don’t confuse it with a real library. Then, imagine in the apocalyptical worst case, having archived only that summary of humankind’s knowledge. There’s a vast amount of detail that WP is just not the right place for.
Well, sure, of course it leaves a lot of material out. But you’d start with Wikipedia surely, then move onto the source material. If Wikipedia leaves out a lot of material, any one of its sources leaves out a lot more.
