Answer 1

A silicone crystal is polished super smooth, then cut into thin squares. A super expensive very precise impossibly thin laser beam then burns a pattern into the crystal. This tricks the crystal into thinking when we run electricity through the pattern. If that makes a CPU sound like magic, then good! It basically is. We’re making atoms dance so we can look at cat pictures and yell racial slurs at people better than us in videogames.
