You can always trust my brother to be ready with cold water to throw on you when you have an idea. The thing is that he is usually right. My point is so what? I think the pessimistic view is right by default most of the time just because people do stupid things, rushing into them headlong. I propose to do stupid things, only with my eyes wide open and with an escape plan. Call it recklessness for intellectuals. (not that I'm intellectual) Pessimism has the effect of preventing success. If you don't try crazy things because you know that 90% of these things are doomed to failure, you lose out on the 10%. And I believe the 10% makes it all worth while. Failure is good!
