What, Me Worry?

David Brin speaks about a problem we have: attacking SF for being optimistic. While I would not be in favor of a constant stream of only happy stories, it can lead to people dreaming...dreaming big...and maybe becoming those who find solutions to our problems. More than one scientist, engineer or explorer has cited the works of Verne, Heinlein, Clarke, Asimov, Bradbury and more as the inspiration for their path through life.
