从个人训练到竞技产业，AI 把"运动过程"变成可计算资产——哪里被吃透，哪里是硬骨头 From personal training to the pro industry, AI turns the act of playing into a computable asset — where it's saturated, and where the hard bones remain

四大版图：个人训练闭环（2C为主）、竞技体育/赛事产业（2B为主）、数据变现与投注层（合规敏感）、中国市场与产业链。每个环节拆传统节点、AI-2C、AI-2B三条线，标出 AI 还啃不动的技术硬骨头。同类产品按规模/影响力排序。红色＝硬骨头，虚线＝市场空白，★＝该格领跑者。 Four maps: the personal-training loop (mostly 2C), pro sport & the event industry (mostly 2B), the data-monetization & betting layer (compliance-sensitive), and the China market & value chain. Every stage is split into traditional / AI-2C / AI-2B, with the technical hard bones flagged. Products are ranked by scale and influence. Red = hard bone, dashed = whitespace, ★ = the leader of that box.
