I pray to never reach a point of cynicism where my response to watching humans leave the planet on a rocket is immediately "meh, whatever, here's my political complaint of the week"

Global hunger's a great example. When we last left the moon (1972) 35% of the global population was undernourished. Today it's ~8%. Optimism is a choice, and generally a more rational one. That doesn't mean we don't have real issues.
