While what I don’t know about the future is probably much more than what I do know, what I do know is also a lot. Dealing with the future is all about 1) perceiving and adapting to what is happening, even if it can’t be anticipated; 2) coming up with probabilities for what might happen; and 3) knowing enough about what might happen to protect oneself against the unacceptable, even if one can’t do that perfectly.
