Isn't pain just a manifestation of a bunch of chemical and electrical signals in the brain and body? It's not "clearly nonsense" to me that you could cause pain by writing a sufficiently long sequence of 0's - for it to be obviously wrong, you'd have to have some understanding of where consciousness comes from.
If you don't understand that, how can you assert that it doesn't come from mathematical relationships?
