I realized the world isn't "magical" it's mathematical
Most things are. At least you can describe it by maths. You just do not know the variables and the rules.
And even if you figure out the rules, there might be some things missing, even if the rules you figured out are good enough for most cases. That's what happened with celestial mechanics. The initial assumption doctrine was Earth in the middle. That made little sense to explain some phenomena. Sun in the middle was better and circular orbits around that big thingy. But no, circular did not quite fit. It was ellipses. But the calculations did not quite get it right. Along came relativity and that the theory is correcter was proven by things like movements of Mercur that could not be explained sufficiently.
Sounds to me, your epiphany was discovering how a math operation that is fundamental for neural networks actually worked and does something. Must have been thrilling. I guess you would be very entertained by yt channels like numberphile and 3blue1brown.
The impressive part is, that we somehow figured out, how to describe a network with maths and implement it with basic logic operations. That's hard. Ironically, it is also very hard for our brain to do logic operations, but recognising patterns and connecting ideas, even having ideas, is super easy in comparison.
The lazy part is, if you use a neural network on your computer, instead of the neural network inside your brain.
