From now to 3000+从此刻，到3000+
Five waypoints on the long arc — the present, the first inflection, the Type I approach, the Type I sustained, and the long horizon. Each one is a plausible mid-point, not a prophecy. Each is what the next 25, 75, 175, and 1000 years could look like if the five horizons are actually walked.长弧上的五个节点——当下、第一拐点、趋近 I 型、稳定 I 型、长远视野。 每一个都是合理的中段坐标，而非预言。它们描述的是：若五条远景真的被踏行， 未来 25、75、175 与 1000 年大致会长什么样。
Globalized planet. Frontier AI in widespread use. Net-zero pathway plotted but not executed. Reusable orbital launch. Pluralism in tension with monocultural backlash.全球化行星。前沿 AI 大规模普及。净零路径已绘制但未执行。可重复使用的轨道发射。多元化与单一文化反弹之间紧张并存。
Continuous off-Earth presence at 10⁴–10⁵ people. Per-capita carbon below 1990 baseline. AI-mediated education default in OECD + China. First multi-decade test of a sub-replacement-fertility civilization.永居地外人口达 10⁴–10⁵ 量级。人均碳低于 1990 基线。AI 中介的教育在 OECD 与中国成为默认。首次以数十年尺度检验『低生育率文明』。
Million+ humans off-Earth. Net-negative carbon globally. Healthspan above 90 for upper-middle income. Functional planetary contracts on climate, AI safety, and biospace.百万级人类居住于地外。全球净负碳。中上收入群体健康寿命 90+。气候、AI 安全、生物太空领域出现可执行的行星级契约。
Solar-system-wide economy. Multi-stellar settlement experiments. Multiverse hypotheses tested through cosmic anomaly searches. Comprehensive wisdom uplift reaching all 8B+ humans.太阳系级经济体。多恒星定居实验。通过宇宙异常搜索检验多宇宙假说。『全面智慧提升』覆盖所有 80 亿+ 人类。
Galactic distribution. Substrate independence (post-biological options for those who want them). Stable equilibrium with cosmic entropy budget. The five horizons fold into a single architecture of civilization.银河尺度的分布。基底独立性（愿者可走后生物路径）。与宇宙熵预算之间的稳定均衡。五条维度折叠为一个文明架构。
