I think it's relatively unlikely that having an agent write graph queries will outperform vector search against graph information outputted into text and then transformed into vectors.
The related issue that I think is being conflated in this thread is that even if your goal was to directly support graph queries, you could accomplish this with a vanilla database much easier than running a specialized graph db
It really seems like this "no PR" idea is having a moment on HN. I can't tell if it's just engagement bait contrarianism or genuine. That any developer would trust themselves even to just not make simple typo's is baffling to me.
Maybe the kernel of a good idea in the comment: A team that prioritizes reviews, such that PR's are not a significant hurdle, is indeed a sign of a mature team.
