A new large-scale study of AI "skills" (SKILL.md packages) found 41,662 of them in the wild, but adoption is copy-and-forget: 53% of reused skills never receive a single update, and 70.3% of linked skill pairs are near-verbatim clones of the registry original. The study, by Haoyu Gao and 5 colleagues from the University of Melbourne, Singapore Management University, and Heidelberg University, mined 18,463 skills from the skills.sh registry and 23,199 personal-use skills across 5,876 GitHub repositories, then recovered 3,709 registry-to-local reuse links. Skills industrialize reuse by packaging procedural knowledge, but the rules governing how agents treat users go almost untouched. Separately, user research job listings for junior staff dry up, and senior staff need AI experience to be hired. Data comics generated with AI increase student learning. Quick view serves as a shortcut for seeing product info. The AI economy has $175 billion in revenue. AI use spreads from peers. Automatically creating advertisements based on a website is also noted.
