Fair point: Terraria was released before Minecraft left beta, redstone (if I remember right) did exist in the beta, but if he seriously felt the need to copy minecraft's redstone, he'd done so earlier.

Not EVERYTHING is copied by another. Hell, even if Minecraft didn't exist, it wouldn't surprise me if electrical engineering would come to Terraria, because it's not all that special and it is something you could expect in Terraria.
