Fairly recently I listened to couple of the geopolitical analyst Peter Zeihan's books on audio and while I don't necessarily take every word as gospel, he presents some very thought-provoking analysis. This is a lecture he gave to an energy group back in September, but he hits on a lot of topics from world demographics to the war in Ukraine and the likely economic and political outcomes. He predicts the Ukrainians destroying the kerch straight bridge here before it happened and explains why, which was pretty prescient. Agree with him or not, there's a lot of food for thought on some important issues here if you find yourself with an hour and ten minutes to kill.
