If we were really to start from scratch, I may be more optimistic. It's just that we have millennia of baggage that don't just go away because we scrap what we are doing and try the opposite. Angry people also don't tend to think clearly and I see way too much anger in the world.
More encouraging experimentation would be nice though! I'm not that old yet!
Experiments are great, how else are we going to figure out what might work :D
