This has some impact on predictive power too. One reason people tried to build the Young Lady's Illustrated Primer is that - more or less, you actually could imagine building that. My friend's daughter talks to the AI, and is learning to read stuff on a glowing screen that knows her name. She doesn't have an abusive step-father, and so fortunately her glowing screen won't need to teach her martial arts for people who are smaller and less powerful than their opponent, and about the importance of running away when there's no way to win. And hopefully her mother will remain a loving physical presence in her life. But the general thrust of the idea in the Primer makes sense, even if we aren't close to "really" building the Primer, ideas from Gibson don't make so much sense.
