That is legitimately so cool; like you ever just sit back and realize how amazing everyday technology is

I respect him for answering questions we didn't even ask

"people in the replies these days take small stuff personal"

So those electrical orbs we played with as kids were really just the first touch-screens.

Even with tech, i'd still miss the X button on the mobile ads

This is a little oversimplified. It’s not just one screen, but multiple. The one described here does use electrical current, but that only tells the phone that it’s being touched, not where. This is when a diamond pattern shaped screen below this comes into play. The diamond have a certain amount of electrons stored within each one of them, the phone has in a way “coordinates” of each of these diamonds. When said diamond is touched, the electrons leave the grid and enter your finger. The CPU sees this and translates it over to whatever is on the screen at that location.
