Its not happening, at least not with LLMs, maybe some future technology will be better with that, but not language models. Writing such a complex software as database engine requires strategy, awareness and rigor. It is somewhat similar to winning a sweaty game of chess with an experienced opponent. LLMs are great with broadness of their knowledge, matching patterns and synthesising that knowledge, but they fail with strategy and awareness part. And this is why they are bad in chess.

I was thinking that this is exactly what ParticleDB is: a random amateur vibe coding a DB. I wouldn't count on things changing much in a couple of years, people will still be people.

It's the old infinite monkeys typing on type writers except now it displaces an entire industry and the only people profiting are the ones holding the tech that powers it.
