Done. Was out by only 17 years on the Principia Mathematica.

Some of the questions made me feel a bit stupid, which is probably a good thing now and then. Had to answer Deist/etc. for the religious identity question, because there wasn't an option for epistemic untheist with Christian ethical heuristics and an admittedly indefensible level of wishful thinking. But "etc." will do :)

Here's hoping we all live to 2100 and find out whether we were right about that stuff.

I think the probability of 90% die-off by 2100 attributable to a single cause is low, but let's face it, an interconnected cascading clusterfuck of 5%-fatal catastrophes would be bad enough, and sadly I think that's more likely. Or I've been reading too much Jared Diamond.
