Let's do a thought experiment here:
If we speed-up an atom to 99-percent light-speed, it would at least travel a distance that could fit around Earth 2 times in 1 second, agree?
And can we agree that, when we "shoot" the atom out, at the Starting line, and when it reaches the Finish line (after 1 second), that it will have passed trillions of atoms? 400 million hydrogen atoms an fit in an inch, a ruler is like billions. Our atom went far, indeed.
And can we agree that atoms have been seen under microscopes where they aren't perfectly aligned with each-other like a atomic-grid? For example, if you make an L made of 3 atoms, and push the top atom over so it's a triangle, that is un-alignment, even over a crack.
--- This means our fired atom not only passes trillions of atoms, but also manyyyy many protons. So instead of saying it passes trillions (of atoms), we should say it passes like quintillions. That right there means there is quintillions of instances/moments/computational-ness each second for a computing transistor!
