"When the last man who remembers the horrors of the last great war dies, the next great war becomes inevitable." The human race is like a giant fuzzing machine

"When the last man who remembers the horrors of the last great war dies, the next great war becomes inevitable." The human race is like a giant fuzzing machine, we just try everything, push every boundary, bad and good, and see what happens. But, our lives are too short for the lessons to last very long, and we repeat our mistakes relatively frequently. We try to encode some of the lessons into social structures, from religion to literature to law, to pass onto future generations. But I can't help but wonder how things would be in this regard if we all just lived an order of magnitude longer. Less war? Fewer financial collapses? I also wonder if less innovation too, but I imagine if the great inventors of our time lived 10x longer we'd get more rather than less, given that it takes an increasingly large portion of a lifetime to learn enough of our growing body of scientific knowledge to be able to make real contributions to it.
