总体看，从 2 月 20 日视频发出来后，这两天迅速扩散，大概有 30%的回应是正面，中立 20%，负面占 50%。这反映了 AI 话题的两极化。一方面，它确实戳中了 AI 发展的痛点：能量是瓶颈，但技术的飞轮不能停。另一方面，技术也不能是真空的，最终得回到对人类生活的帮助和改善上。或许，如 Altman 所说，得建更多清洁能源是一种解法，但也如批评者言，无论未来出路是什么，得尊重人类独特价值。
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.
