I think the problem is the answer to this question: What is harder regarding computation - arranging for a computation or doing the computation? What I mean is that the computation of an addition or subtraction is easy but the arranging of instructions of code into an algorithm is hard. Everything has to be in the right place for the algorithm to work right. This is why packaging is so difficult. Each algorithm and code expects things to be in a certain place. ABIS and packaging for them is tedious.
