> basically how does the information translate from mere electronic impulse to interactive reality?
If you had ever interacted with a taser you would not be of the impression that electric impulses are somehow not part of reality.
Electric impulses are quite real. Turning a current on or off can do things like manipulate lights, or electric motors to create movement. Images on a screen are just a bunch of tiny lights in a certain pattern, and sound is created by vibrating air using electromagnets.
High resolution images, complex audio, and things like this website are just complex combinations of these signals. How to get from on and off to that complexity is a huge topic but hopefully this addressed your core question of the transition from something you considered “unreal” to “tangible reality”.
