During a Berkeley meeting of the Manhattan Project, Edward Teller brought up the basic idea behind the hydrogen bomb. You would use a nuclear bomb to ignite a self-sustaining fusion reaction in some other substance, which would produce a bigger explosion than the nuke itself. The scientists got to work figuring out what substances could support such reactions, and found that they couldn’t rule out nitrogen-14. The air is 79% nitrogen-14. If a nuclear bomb produced nitrogen-14 fusion, it would ignite the atmosphere and turn the Earth into a miniature sun, killing everyone. They hurriedly convened a task force to work on the problem, and it reported back that neither nitrogen-14 nor a second candidate isotope, lithium-7, could support a self-sustaining fusion reaction.

They seem to have been moderately confident in these calculations. But there was enough uncertainty that, when the Trinity test produced a brighter fireball than expected, Manhattan Project administrator James Conant was “overcome with dread”, believing that atmospheric ignition had happened after all and the Earth had only seconds left. And later, the US detonated a bomb whose fuel was contaminated with lithium-7, the explosion was much bigger than expected, and some bystanders were killed. It turned out atomic bombs could initiate lithium-7 fusion after all! As Ord puts it, “of the two major thermonuclear calculations made that summer at Berkeley, they got one right and one wrong”. This doesn’t really seem like the kind of crazy anecdote you could tell in a civilization that was taking existential risk seriously enough.

They're basically the same when considering the other orders of magnitude. I think the main point is about expected value.
Something along the lines of, engineered pandemics are might be likely to happen, but less likely to kill everyone than unaligned AGI. We'll probably have rich assholes hiding in bunkers for 200 years if an engineered pandemic kills everyone else, and they'll eventually come out to repopulate Earth.

I don't even get how they get those numbers with any degree of accuracy.

It's always the most retarded most scientifically illiterate morons who are the most confident in making these sort of retarded critiques. You obviously don't understand science and don't have any expertise in the subject, so what makes you think you know better than actual scientists. Maybe you should focus on your own ignorance and stupidity instead of criticizing scientists and experts who have a lot more training and knowledge than some fear-mongering internet conspiracy theorist like yourself.

I'll make this easier. """biosecurity""" is a suitcase word. You can throw lots of definitions into it.

Research into advancing gain of function is a double edged sword.
If it's an easier metaphor, we can use asteroids. Imagine we develop the technology to knock an asteroid off course so it doesn't collide with Earth. This is a good technology to have, but would only be useful every 1 million years or so. Now that we have the technology to knock asteroid off course, everyone now has the technology to knock asteroid on course with earth. If one crazy billionaire anytime in the next 1 million years decides to hit Earth with an asteroid, that technology will have actually been bad.

Consider observer bias. Do you hear about every failed terrorist plot, or just the ones you're supposed to hear about?

>Why are we so concerned about nuclear war
Because of what's called countervalue doctrine. There are two prevailing nuclear war doctrines: counterforce and countervalue. Countervalue is when you nuke cities. The scary part of nuclear war is that a limited counterforce conflict could easily escalate into a large-scale countervalue conflict.
>fallout
Not really a concern in most situations. Fallout only gets generated in significant amounts from groundbursts, where dirt and debris gets irradiated and kicked up into the air. Airbursts, besides being more destructive in most situations, produce very little fallout.
>nuclear winter
Largely discredited today. The same people who predicted nuclear winter also predicted a regional climate crisis from the burning of Kuwaiti oil wells in 1991. No such climate crisis occurred. So the nuclear winter hypothesis got badly discredited and has since pretty much been ignored.
