Really interesting read and video. I honestly had no idea that so much chemistry was involved in the manufacture process! However, I probably should have figured so... Anything being manufactured at that scale would require the precise alignment of atoms to achieve the desired outcome. It has to be too perfect. Crazy what people have come up with these days and to think floppy drives were the "thing" not too long ago...
