其二，在模型的训练阶段，人类标注员的工作之一是给 AI 的回答打分。通常条理清晰、全面详实、结构对称的答案会得到高分。单纯使用 AI 撰写行业报道，在目前这个时间点，水平只能算将将及格，但远不及一线行业媒体作者，靠行业经验所产生的观点和洞见。
Finally, to address the slow and weakly consistent S3 reads, the database leans on lock-free B-link trees. That lets readers keep moving while background checkpoints/updates by clients split or reorganize index pages. In B-link trees, each node points to its right sibling. If a checkpoint splits a page, readers just follow the pointer without blocking. Since update corruption is still a risk, a LOCK queue token ensures only one thread checkpoints a specific PU queue at a time. (I told you this is complicated.) The paper admits this is a serious bottleneck: hot-spot objects updated thousands of times per second simply can’t scale under this design.
