Es una lección invariable a la humanidad que la distancia en el tiempo, y asimismo en el espacio, da perspectiva a las cosas. - Isaac Asimov

Science doesn't purvey absolute truth. Science is a mechanism. It's a way of trying to improve your knowledge of nature. It's a system for testing your thoughts against the universe and seeing whether they match.

Saying something is 'too bad' is easy. You say you disapprove, which makes you a nice person, and then you can go about your business and not be interested anymore. It's a lot worse than 'too bad.' It's against everything decent and natural.

Any technological advance can be dangerous. Fire was dangerous from the start, and so (even more so) was speech — and both are still dangerous to this day — but human beings would not be human without them.
