Ok, I understand your negativity. People are often pretty negative about the problems I work on (software patent lobbying). When I ask people to help, some say it's a waste of time trying to take on the software industry and the patent offices.
Sometimes it does feel like trying to hold back the tide, but if we weren't working on it, we'd miss every opportunity. There are never any obvious ways to easy victory, and like Val's doc, we've written down great advice years ago. Now we're working on bridging the gap to make that advice a reality. Sometimes we do win, and maybe in a decade or two we will have won. But my point is that this work has made me less negative about working on the same impossible problem again, and again. The other option (not trying) would be worse.
