If we assume that there is "something significantly wrong with our current understanding of the world" but don't know anything more specific, we can't come to any useful conclusions. There's a huge number of things we could do that we think aren't likely to be useful but where we might be wrong.

So is writing this book something we should do (as the original comment seemed to suggest)? No. But I agree it's something we could do, is very unlikely to be harmful, and is neat and fun into the bargain.

With that said, I'm going back to working on my cool, neat, fun, non-humanity-saving project :-)
