As for Spielberg's intentions to once again adapt a lost Kubrick masterpiece, the uninitiated may smirk, but there is still no questioning his skill as a director. In fact, while Spielberg could have benefited from his colleague's artistic prudence, his powers as a producer and his ability to get projects made are second to none.
I'm very fond of conspiracy theories - they're intriguing and fun, in their twisted way. But they're also very frustrating, because any big reveal will always be just out of reach, always just around the next corner. You want them to be true, and maybe some day they will be, but they're never true now.
