do you feel like it needs a major architectural change or breakthrough leap in abstraction before it can provide business value in software development, or would far larger context window sizes be enough for it to provide substantial value already?

For me it feels like it just starts to break after a certain length, but may not require a breakthrough new architecture to provide more value. Just larger context window sizes, so it can do the same thing it does on smaller pieces of code, on larger pieces of code, too.
