Worse, with code, you might be able to read all the parts in order to figure out what it does - given the language and/or the CPU architecture. With biology, the code is running against nature, so the instruction set includes assumptions like "but if these two get close enough, then this other reaction occurs first". I suspect it can get so complicated that the only way to find out what it does is to run it.
