I just finished reading the article. Overall I think it is a well structured and written article. I like how you are naturally referencing all major citations. Regarding the human extinction events is important to me also, so I was naturally inclined to read this article as deeply as I could. One major thesis of the article is showing that these are non-linear threats. With climate change and some recent discoveries of methane gas melt from the arctic tundra, there is a risk of further accelerating a system runaway affect that scientists are still trying to understand. The climate scientists are at a frontier here and I wish them well. Greenland ice sheet volume loss is also another worrying point. So I would put climate change possibly higher up the list. Asteroid risk is hard to quantify (Elon Musk had also publically mentioned this point and hence his pivot to Mars). Recently he has also made Tesla Solar and that is an important step because he is also concerned about energy and possibly even decentralization (although he isn't publically acknowledging it right now). I've had chats to Nick on this and he also agrees. I also like how you are actively trying to analyze from a statistical and mathematical perspective and delve deeper into the abyss of the layers of under ground politics. One thing I know and it's proven in history (the election itself is one thing, actually following policy frameworks and promises is completely another). Also the voting system itself needs a completely independent third party to audit the counting machines themselves. (If only it were a public and well secured blockchain...)
