This is a fantastic article!! I'm writing a sci-fi novel and your writing helps me understand my own thinking processes and the resulting discomfort when I leap to what you call a "guess", NOT a prediciton. Now I feel more confident in wriitng a book that some people may inevitablly criticize for being a ridiculous set of predictions. No, dude, they're GUESSES. I can't possibly predict the future. Thank you so much for this! RR
