Yes, I've also read that first paragraph of Wikipedia as well, but the question was where did the word "voxel" come from. It was also joke extension on what @BrodieOnLinux posted (to which I replied and wrote that post)😉

But if you are actually looking for an answer, the etymology of voxel is vo(lume) + (pi)xel
