It isn’t clear that the offense-defense balance directly affects the number of deaths in a conflict in the way that you claim. For example, machine guns nests benefitted the defenders significantly, but could quite easily have resulted in there being more deaths in warfare, due to the use of tactics that hadn’t yet accounted for them.
If you had told people in the 1970s that in 2020 terrorist groups and lone psychopaths could access more computing power than IBM had ever produced at the time from their pocket, what would they have predicted about the offense defense balance of cybersecurity?
I don’t know why you’d think that compute would be the limiting factor here. Absent AI, there are limited ways in which to deploy more compute.
Will be quite curious to see if this conference is sufficient to revive this forum.
