Concurrency, Christmas, and the Ultimate Programmer

Reflection on Life and Concurrency

It’s the Christmas season, and I’ve been reflecting on something that has fascinated me since I was a child.
There are billions of people in the world, all living different lives, making choices, building dreams, and facing struggles simultaneously. Life does not take turns; it runs in parallel. Sometimes our paths intersect, sometimes they do not, yet everything keeps moving.

Concurrency in Computer Science

For a long time, I could not fully wrap my head around this. Later, while studying Computer Science, I encountered the concept of concurrency—the idea that a system can manage multiple tasks simultaneously. Independent threads execute in parallel, coordinated by scheduling, synchronization, and shared state. That was the moment it clicked: human life itself is concurrent. Long before we gave this idea a formal name in computer science, it already existed in reality—billions of independent processes, each with its own context, yet somehow progressing without total collapse.

Spiritual Perspective

To me, that points to something deeper. I cannot help but see God as the ultimate Programmer—not just writing code, but designing a system where countless lives run at once, governed by purpose, timing, and order. Christmas reminds me that behind the complexity of life is not randomness, but intention. God did not just create life; He engineered it.
