The futures we imagine contain some details that our brains invented and lack some details that our brains ignored. The problem is that our brains fill in and leave out. God help us if they didn’t.
No, the problem is that they do this so well that we aren’t aware it is happening. As such, we tend to accept the brain’s products uncritically and expect the future to unfold with the details—and with only the details—that the brain has imagined. One of imagination’s shortcomings, then, is that it takes liberties without telling us it has done so.
