I don't see how hedging about development of a particular technology is a bad thing. We have expected CPUs to get faster, but it didn't get there. Some people were presumably hedging against it, and now we've routed around this with multi-core computers. People might have expected flying cars, yet they didn't come to be. Instead, quick communication has been solved by the Internet. The world has many ideas, and they can be explored simultaneously, but we also must face the possibility of failure in case we paint ourselves into a corner, like we just did with the global warming. I find broad exploration rather optimistic compared to being single-minded about something happening in the future.
