Git packfiles use delta compression, storing only the diff when a 10MB file changes by one line, while the objects table stores each version in full. A file modified 100 times takes about 1GB in Postgres versus maybe 50MB in a packfile. Postgres does TOAST and compress large values, but that’s compressing individual objects in isolation, not delta-compressing across versions the way packfiles do, so the storage overhead is real. A delta-compression layer that periodically repacks objects within Postgres, or offloads large blobs to S3 the way LFS does, is a natural next step. For most repositories it still won’t matter since the median repo is small and disk is cheap, and GitHub’s Spokes system made a similar trade-off years ago, storing three full uncompressed copies of every repository across data centres because redundancy and operational simplicity beat storage efficiency even at hundreds of exabytes.
其次，学前阶段是大脑发育关键期，AI的即时满足会让孩子失去耐心，专注力变差。更隐蔽的是，AI永远顺着孩子，不会反驳和生气，孩子长大后受不了一点挫折，不会处理冲突。总之，AI可以当工具，但不能当“电子保姆”，这是家长要万分警惕的。
