>How can humans not be the cause humanity's biggest problems?

Think in simpler terms, like a technology used at work, or a tool used at home; I've been in enough changes in the former that tell me many people believe a new thing will be better than the old thing, even after going through that same process several times.

The introspection needed to understand that people will break the process if they want or need to is hard to come by.
