The cool thing with software engineering is that we can drive the costs of building the same project repetitively down to zero. We don't have to write Postgres from scratch each time we spin up a CRUD app, we can just install it. I think that's why estimation in software engineering is difficult. The predictable repetitive portion of the project takes up no time - all that's left are the novel unknown parts.
