No, we should have a DNA element that is created with the right amounts of oxygen, carbon, hydrogen, nitrogen, acetic acid, and 300 more molecules. And zooming should go up to the subatomic level so we can edit quarks and stuff.
You know, I was thinking that PT should have "SMET" or Smart Metal. This metal doesn't allow spark to reach the other pieces of metal next to it, just in the direction that spark was going.
