@kabes author here. I've been wondering the same actually. My doubts about AI is that it just writes code, and does not really provide battle-tested blocks, which instead a top-down approach might provide.
@yobbo author here. Totally agree on my contributions being negligible ;) That being said, doesn't that actually prove the point? If a good amount of business value is coming from gluing pieces together, why not start from the top?
