2022 年 11 月 28 日，我们发布了一款非常简单的小程序，叫做墨问便签。当时我在这个产品上写了一条笔记，叫墨问便签 demo 版本已经发布，并配了一张图。这条笔记获得了 1400 多次阅读和 260 多个赞，仅此而已。今天，我用当下的墨问重新生成了这张卡片，可以看到这张定制卡片上多了 Pro 会员的标识，是的，墨问这款产品进入了一个新阶段。迭代至今，墨问便签有了丰富的笔记展现能力，有多种评论互动方式，有个人主页、付费订阅、AI 语音笔记、AI 听读、画廊和微信群权限等，墨问不仅成了创作者工具，还是微信里的私域运营工具，我们有了近百万用户和几十万用户笔记。数万创作者在墨问获得了收入，最好的创作者收益达几十万元。墨问西东公司也在依托墨问这款工具进行商业闭环。但是还不够。墨问便签发展到现在，工具属性凸显，付费订阅成了工具属性的一部分。我们希望设计更多的创作功能，比如 AI 写作、AI 知识萃取、双链、丰富的编辑器、赞赏、问答、墨问收音机……通过 AI 能力、存储能力等基础设施，让墨问用户能更好的记录生活、生产作品，并服务自己的用户。这些都需要更多资源。为了产品良性发展，我们设计了 Pro 会员体系，并开启新的十年之约。我们在当前阶段为 Pro 会员提供了如下功能：50G存储空间/画廊/生成AI听读语音/10分钟AI语音笔记/单篇20000字笔记/无限制的付费订阅/会员定制分享卡片 ...继续阅读 (5)

在诺贝尔经济学奖至今为止的56次颁发中，今年或许是最令人失望的一届。前言笔者读了2024年诺贝尔经济学奖得主推荐的三本书，其中《国家为什么失败》和《自由的窄廊》像是西方宪政政体的理想童话，类似于福山历史决定论的观点，三位作者吹捧赞美民主宪政体制的包容性，试图证明包容性制度和宪政民主政体是通往繁荣和自由的唯一途径。相比之下，《权力与斗争》通过分析工业革命，探讨了技术增长带来的不平等问题，并对当下AI发展的影响发出了悲观的警示，呼吁政府关注技术进步带来的社会不平等。总的来说，《国家为什么失败》和《自由的窄廊》并不值得一读，而《权力与斗争》的政策建议则颇具启发性。以下是我在阅读过程中收集的数据资料。TL DR在诺贝尔经济学奖至今为止的56次颁发中，今年或许是最令人失望的一届。2024年诺贝尔经济学奖的获奖作品，包括《国家为什么失败》和《自由的窄廊》，延续了西方宪政民主的叙事框架，将包容性制度视为经济发展的核心动力，主要存在以下问题：制度决定论的单向视角：通过对南北美洲殖民地历史的分析，作者试图将经济差异归因于“包容性”与“掠夺性”制度的形成，忽略了制度之外的历史、地理和文化因素。其结论过于简化，将殖民的历史创伤包装为现代化的制度演化过程。西方中心化偏见：作者将西方民主与包容性制度划上等号，忽视了其他文明形态的多样性与独特性。这种理论不仅无法解释非西方国家的制度演化路径，还隐含了文化优越主 ...继续阅读 (4)
