I read a book back in college (wish I could remember the title or author) that talked about the "technological imperative." The notion is that, collectively, we have no ability to exercise judgment about which knowledge and capabilities are desirable or undesirable. Rather, the book argued that once mankind acquires the ability to do something (e.g., create a nuclear bomb) some member of the species will do it. I think that argument has a lot to it, which leads me to say that mankind is self-destructive albeit unwittingly.
No, not in general for in the heart of men is still the hope for a better tomorrow... not only for ourselves but for our children. I think man's greed, however, will lead to the destruction of our planet.
