Yep, I still remember the feeling when I first developed at least some mental model for all the steps along the way from "enter" to seeing the results, and realized that it was even more shockingly complex than I imagined it to be when it was just magic, and that despite that complexity, it all actually works many billions of times every moment of every day.

Then what happened is that pretty much every year (maybe closer to every day) since then I have learned about some piece of the puzzle where my mental model was actually nowhere near the truth, and that each individual puzzle piece is even more complex than I thought! Truly wild stuff.
