I think the colloquial understanding of "science" means studying how the world works. This is more like engineering: exploiting our understanding of how the world works to build new capabilities that we don't fully understand.

I don't think you would call it "science" for a bunch of single cellular organisms to cooperatively evolve a multicellular one. Similarly you wouldn't call it science when humans create digital lifeforms that require actual science to be done to understand how they work.
