I feel like this article was circling a point it never actually got to. All the advice in here (except controlling scope creep) is specific to a TUI with an elm like architecture.

But here's the thing, you almost never know what the architecture is up front. If you do you probably aren't the one writing the actual code anymore. Writing the code, with or without an AI is part of the design process. For most people it isn't until they've tried several times, fucked it up a bunch, and refactored or rewrote even more that you actually know what the architecture needs to be.
