Much like science in general, these topics are never -- and can never be -- considered settled. Hence why we still experiment with and iterate on architectural patterns, because reality is ever-changing. The real world from whence we get our input to produce desired output is always changing and evolving, and thus so are the software requirements.

The day there is no need to debate systems architecture anymore is the heat death of the universe. Maybe before that AGI will be debating it for us, but it will be debated.
