> We'd have to re-engineer a lot of things that aren't just off-the-shelf to do it again. Yes. I think this is the perspective that people trend to overlook - every engineering project is unique, in the sense that it's optimized to do the job under very specific constraints - costs, production capabilities, available materials, etc. When the circumstance changes, sometimes you simply can't just pull the same blueprint out of the archive to make another one - redesigning it is sometimes unavoidable, even if the older design is nothing wrong from a technical point-of-view. I think the same applies to software development.
