Oh it's natural to want to change the world and assume the old folks and their old ways won't work in the "new world". We were all there. The trick is to learn the lessons and avoid repeating the mistakes. Not everything the previous generations did was incorrect. Most everybody I've ever talked to will agree that as they got older, they realized how little they really knew when they were younger.
I know that I don't know everything. I know that I don't even know most things. I know I'll have very little impact on the world. I know some things need to change. I know some things need to change back. I know your generation messed up. I know the generation before you messed up. I know my generation has messed up and will continue to mess up.
Other than that, and pharmaceuticals, I don't know much.
