Like any "futurist," fortune teller or psychic, the accuracy of his predictions is based on having even the slightest clue, making vague or broad enough predictions that they're almost universally applicable, and relying on selective memory to erase all the predictions you made that didn't pan out. (Like some war with China that was mentioned in TFA.)
Which isn't to say that a think tank devoted to thinking about future wars and military tactics or strategies is a bad idea, or charlatanism, just to say that his ability to predict the future is being wildly overstated. I'm sure he has a sharp military mind, and good analytical skills to make the correct predictions he did, but that's a far cry from predicting the future.
I mean, I knew Google was going to be huge before their IPO... now that their stock's over $1,00 per share, does that qualify me as a technology or stock market futurist?
