In your 'sayings' early and late are ambiguous. As far as investing is concerned being right in a prediction means you profited, so the early-late error bar is defined by the time in which you could profit by your prediction. Applying this same rationale here the early-late error bar is harder to define, since profit is not clear and somewhat subjective. So taking some liberties with early-late and right-wrong is I feel appropriate. Taking into consideration that these predictions are 5+ years old I think they are pretty good. He clearly spotted several trends whose future significance was at the time not obvious. If someone started a business believing one of these trends had promise it is possible that the business would have been successful. I do feel that for what he was trying to accomplish being early or late by a couple of years or off on a detail but correct in spirit is not significant. Also, I think it is important to add that making predictions like these is very important becuase the future develops from our perceptions of what it will be.
