This is all too harsh though. When you are doing something new, you aren't that sure what kind of extensibility and modularity you need internally, so you wind up over engineering and over architecting. Imagine you wanted to build a bridge without no one ever doing that before. It is an open problem, the resulting bridge might work, but it won't be pretty and probably used way too many materials, meaning it will be difficult to repair and upgrade.

But your next bridge will be better, benefiting from the experience of the previous one, and you might be able to even do some design up front for the third one that actually sticks.

Tl;dr get started on your first bridge early.
