The demographic fueling these purchases has also shifted. First American’s data show that gains in education and earnings have strengthened single women’s buying power over time—the share with a bachelor’s degree or higher rose from 20% in 2000 to 35% in 2025, while real median income climbed from roughly $42,000 to $51,000. The trend mirrors another, broader shift: just 47% of U.S. adults are now married, according to census data, down from prior decades，推荐阅读新收录的资料获取更多信息
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.，这一点在新收录的资料中也有详细论述
LeCun says AMI aims to work with companies in manufacturing, biomedical, robotics, and other industries that have lots of data. For example, he says AMI could build a realistic world model of an aircraft engine and work with the manufacturer to help them optimize for efficiency, minimize emissions, or ensure reliability.
