With no offense meant,,,Thank you for the opening sentence after the Q.
The Q suggests no choice.
Certainly the past is old news, and obviously we don't all "learn" from it.
Many don't have a "Plan" and perhaps still might not, if they could "know" the future.
I also like the fact that you used the word "unavoidable",,,and perhaps "seeing" OUR personal futures would only cause stress and degradation?
My personal feelings are that to know it is to deny any surprise, negative or positive, and more,,, the challenge to use cognitive thought in dealing with what happens.
One aspect of our species is that we also, often, deny that consequences,,,negative or positive,,, are the result of ANY actions we take in the NOW.
