高端电动两轮车市场的 “增量空间”，值得商榷。中泰证券测算的 “一线 + 新一线城市年销量增量 660 万台”，建立在 45% 渗透率的理想假设之上，但现实是，北京、上海等特大城市公共交通体系完善，两轮车渗透率天花板仅 40%-50%，且九号已占据高端市场半壁江山，向上的增长空间几近枯竭。而新一线城市因地形、地方政策、公共交通配套的差异，两轮车保有量存在显著方差，并非单纯依靠产品升级就能实现市场渗透，九号的拓店计划在重庆、成都等低渗透率城市已遭遇明显的水土不服。
Understanding the potential epistemic impact of sycophantic AI is an important challenge for cognitive scientists, drawing on questions about how people update their beliefs as well as questions about how to design AI systems. We have provided both theoretical and empirical results showing that AI systems providing information that is informed by the user’s hypotheses result in increased confidence in those hypotheses while not bringing the user any closer to the truth. Our results highlight a tension in the design of AI assistants. Current approaches train models to align with our values, but they also incentivize them to align with our views. The resulting behavior is an agreeable conversationalist. This becomes a problem when users rely on these algorithms to gather information about the world. The result is a feedback loop where users become increasingly confident in their misconceptions, insulated from the truth by the very tools they use to seek it.
