I like going deeper, just imagining the stupid number of atoms, interactions and things even someone with vast knowledge about don't truly understand.
And to add more, I play games via cloud gaming, and even after thousands and thousands of hours with it, it blows me away all the time.
An electric impulse in my brain sends a signal to my finger which then presses a button on a device that sends a signal to another device, computer, then another device, router, then many many other devices along the way to the server centre where a computer reacts to that signal and changes something in a stupidly complex simulation, then the visual, audial and haptic responses are calculated and sent through all those devices back to my screen and to my experience it seems instant.
So many incredibly complicated things happening thousands of times every second and traveling thousands of miles back and forth and for hours on end with very few failures. It's just astounding.
