"a repeatable process would be immediately automated away by writing a function, library, framework or any such tools" This is the crucial point here. Source code is a (almost) self-assembling blueprint. The actual product that will be build is the software and software is a configuration of matter, in this case of a computer. The source code/blueprint for a house is not self-assembling. Compiling such a blueprint requires you to configure the building materials in a way that they become a house. With better robotics, we will probably get there at some point in the future. And with software we will always be in a place where you either do new stuff the first time manually or with crappy tools the 100th time.
