Nice essay, C.C.! I think you make an excellent point with just a few simple words: "Who would have it any other way?"
The fact that there is some balance between predictability (the Sun rises and sets every day, the seasons come and go at regular intervals, rocks don't just spontaneously turn into elephants) and unpredictability (you never quite know where life will take you next, and you can't exactly predict what other people will think or do) is precisely what makes life tolerable, in my view. Would you really want to know the future if all your future actions were predetermined, and there was nothing you could do to change them? I wouldn't. Life is better with the uncertainty of tomorrow.
In a way, I guess, it's nice that the conclusion of lots of high-minded sciency arguments matches the common sense view that we can't exactly know what tomorrow holds.
