POD is sometime between 1900 and 1914, but that doesn't matter much here because I'm wondering how technology will develop through the 20th century with no world wars rather than how politics and diplomacy will play out. If the century was peaceful in the Western world, how would things like aircraft and electronics develop? By 2016 is there a chance that jet planes and rockets would still exist? Would there be large passenger aircraft? Would cars still contain almost no electronics? It's interesting to think about this since the world wars advanced technology so much in such a short amount of time.
