I do not feel that world is heading towards another world war as it happened in the XX century. Why? Putins daughters live in Europe/US. Same for childer of other Russian top government officials. Same for China. Who will go for total war? On the brink of the war western military may assassinate the top government officials of the enemy hawk faction using fly-bots or some other kind of high tech minidrones. I have no information on the current capabilities though I've read about some of those being developed. Asteroid mining will change the incentive structure for total war. Further AI development will change the incentive structure for total war. The world becomes less violent with every passing year. Look at the gapminder data. We will see lots of local conflicts, hunger revolts, sectarian violence, mechs-human battles in Middle East and other futuristic tropes though.
