The Baby Boomer generation's influence is waning and I'm optimistic that the next generations who did not grow up in a period of extreme mutual distrust like we saw post-WW2 and during the Cold War will be better suited to lead.
It's going to take us, as a global group of people on the planet, a long time to unwind a lot of the hawkish and nationalist policies that have evolved over the past 150 years. Certainly there will be periods where charismatic leaders with latent agendas drag us backwards and temper the progress, but ultimately if each successive generation is even just a bit more inclusive and globally considerate than the last, we'll find a way to make this work.
