This blog has a brilliant insight that I still remember more than a decade later: we live in a fantasy setting, not a Sci-fi one. Our modern computers are so unfathomable complex that they are demons, ancient magic that can be tamed and barely manipulated, but not engineered. Modern computing isn't Star Trek TNG, where Captain Picard and Geordi LaForge each have every layer of their starship in their heads with full understanding, and they can manipulate each layer independently. We live in a world where the simple cell phone in our pocket contains so much complexity that it is beyond any 10 human minds combined to fully understand how the hardware, the device drivers, the OS, the app layer, and the internet all interact between each other.
