Dude, none of these are gonna be considered "major." If you were to travel to the year 2500 and asked people about COVID-19 or the war in Ukraine, only huge history nerds would have any idea of what you're talking about
I think that the first AGI, which will probably be this decade, will be considered a major historical event by 2500, just like how we still consider the invention of the printing press a major historical event.
If the Ukraine war ends up escalating into WW3, I think that will count as well, unless we get up to like WWX.
If David Grusch is right, I think disclosure would make that list.
Accidently used the downvote button as a disagree button but I undid it and am leaving this comment instead. I personally think agi is uncomfortably close to the horizon. A lot about our lives is going to fundamentally change very quickly IMO.
You mean we're not still talking about the Cocoliztli epidemic and the Eighty Years' War?
You're setting the bar a little high by putting us 500 years in the future, though.
I think things just 100 years or so ago can be considered "major", and COVID-19 and Ukraine might both make the bill.
