Over the past 5-10 years I've gone from being mostly optimistic about our collective future to quite pessimistic. It's looking increasingly likely that we're unable to solve problems like climate change that require mass cooperation and that too many people are too selfish and short-sighted to allow for collective action. And in the (hopefully unlikely) event that industrial society collapses (from a pandemic, mass political instability, etc) any surviving humans won't be able to restart it because we've already used all of the "easy" fossil fuels. This is pretty much our only shot at making civilization work.
