As far as I know, articles of Ancient Greek adhere to roughly the same declension rules as nouns, with a little bit of irregular changes. And as for modern languages like Italian and French, their articles, while being irregular, are mostly inherited from Latin demonstratives ille, illa, illud, knowing this might help memorize the many forms.
What you described does not qualify as a good fantasy either. There needs to be rules even in the world of magic, and eventually so called hard fiction and fantasy only really differ in the way how they present the fantasies.
There is a book I love: Lord of Light by Roger Zelazny, in which he first wrote about fantasy figures with magic powers in Buddhism tales, and then revealed that they were just humans with high tech and play gods to those who don't.
The point is replacing humans, and for that it only has to equal them at lower cost (including factors like not needing sleep and being easily clonable). The outperformance lies in the cost savings, not necessarily in the intelligence.
I have setup a gitea instance on my gitea server which I think is good for me and GitHub both. For one, I dont have to worry about GitHub service outages, and GitHub gets to be free from my toy (and mostly AI slop) projects that no one else will ever read/use/participate in :-)
