It’s not necessary that 2⁄3 of the people who ever live be alive simultaneously. It’s only necessary that the last humans not a) all die simultaneously and b) constitute more than 2⁄3 of all humans ever. You can still have a last 2⁄3 without it being one giant Armageddon that kills them in one go.
I agree in principle, but I’m curious as to how much one is stretching the term “doomsday.” If we never develop true immortality, 100% of all humans will die at some point, and we can be sure we’re part of that 100%. I don’t think “death” counts as a doomsday event, even if it kills everyone. Similarly, some special virus that kills people 5 minutes before they would otherwise die could kill 100% of the future population, but I wouldn’t really think of it as a doomsday virus. Doomsday need not kill everyone in one go, but I don’t think it can take centuries (unless it’s being limited by the speed of light) and still be properly called a doomsday event.
That said, I’m still curious as to what evidence supports any claim of such an event actually happening without narrowing down anything about how or when it will happen.
Sure. But the human species can go extinct on one day without a vast number of humans dying on that day. Maybe it’s just one little old lady who took a damn long time to kick the bucket, and then finally she keels over and that’s “doomsday”.

Unless I missed something, “doomsday” just means the extinction of the human species.
Doesn’t it refer to the day of the extinction? “Doomsmillenium” doesn’t sound nearly as good, I think.

That’s what Psychohistorian was saying shouldn’t be called doomsday, and I tend to agree.
Yes, and the doomsday argument is not in regards to whether or not doomsday will occur, but when.
