The Future We Already Lived

You can predict the next second. That is not impressive. It is just how time works at close range. Nothing surprising is going to happen in the next second so you already know what it contains.

Now stretch that a little further. Not a second but a few weeks.

Before I traveled to India I was stopped at a red light and deliberately planted a thought: "After I come back I will stop at this same signal and remember that right now I already knew this moment would come."

It is the same thing as predicting the next second. Just stretched. The trip was going to happen. The return was going to happen. The signal was going to be there. None of it was uncertain. So I already knew.

When I came back and stopped at that signal the memory arrived exactly as planted. Of course it did.

This Is Just Integral Calculus

Predicting the next second works because the interval is so small nothing can change. Stretch the interval and it still works as long as the function is smooth and already defined.

That is integral calculus. The integral does not wait for you to live through each moment. It already contains the total across the entire interval. The answer exists before the journey does.

My life for those few weeks was a smooth already defined function. Trip, return, signal, memory. No discontinuities. The integral was readable before I lived it.

The only thing I did at the red light was read it. Then tell my future self to notice.

Now Extend It to 100 Years

The same function keeps going beyond me.

Those few weeks before and after India just passed. Smoothly, mechanically, exactly as the integral said they would. No friction. Just time moving forward the way it always does.

100 years will pass the same way. Just like that. The same effortless indifferent unfolding. And you won't be there. That is the unsettling part.

The future is already decided. We just move through it and experience it one moment at a time.
