来西藏之前，我没有任何预设，甚至是临飞前一天才买的票。但来了之后，发现这是一个完全脱离我的新的世界观。 在这个世界观里，其独有的文明可以被理解为一套长期运行的人类智能系统。这套智能系统，其实就是文明的世界模型。 每个人都有自己的世界模型，来自家庭、教育、经历、创伤等；而文明世界模型是共享的，包括语言、宗教、法律、教育等；再往上就是现实世界，不管我们的模型是什么，现实都会不断给出反馈，如果预测失败，模型就会更新，直到成功变得稳定。 而且世界上存在很多彼此自洽的世界模型。以前，我们很容易把自己的世界观当成”现实本身”。但到了西藏，会发现，很多人真诚地生活在另一套解释体系里，而且这套体系支撑了他们的伦理、情感、日常生活和社会组织。 这未必意味着哪一套就是唯一正确的，但它会促使人区分两件事： 现实：客观世界本身。 世界模型：我们理解现实、预测现实、赋予现实意义的方式。 所以不是要接受某一种世界模型，而是开始观察：不同的人、不同的文明，是如何建构自己的“地图”，又如何依靠这张地图生活。这也是认知科学、AI和人类学都非常关注的问题。 AI也在试图构建和运用一种对世界的内部表示，只不过它依赖的是数据、训练和推理，而不是社会制度和文化传统。最终的落脚点，无论是AI还是人类文明社会，都会落在： 一个复杂系统，是如何形成稳定的世界模型，并让它跨越时间、跨越空间、跨越个体而持续运转的？

when the dream becomes the job i used to think the dream was to make my hobby my work. to spend my life close to the things i loved: computers, tools, interfaces, systems, tiny details, the feeling of making something from nothing. the things i used to do at night, after school, after work, in the margins of life, somehow became the center of my life. and it is a dream. i don’t want to pretend otherwise. there is a very specific happiness in getting paid to care. in meeting other people who care. in building a language around your obsession. in seeing something that lived only in your head become real enough for other people to touch. but there is also a quiet pain in it. because the thing that once belonged only to you no longer belongs only to you. it becomes attached to deadlines, teams, customers, strategy, money, reputation, momentum... curiosity becomes roadmap. taste becomes decision-making. play becomes output. the thing you once used to escape the world becomes the thing through which the world reaches you. and now there is another strange layer: the machines are getting good at the work too. not just the boring parts. the parts that used to feel close to the heart. writing, coding, designing, reasoning, making taste-like decisions, turning vague ideas into something real. the things we once used as proof that we had something special inside us are becoming things a model can approximate, remix, and sometimes do faster. that can feel scary in a very specific way. not only because of jobs or competition, but because it touches the myth you built around yourself. if the thing i became good at can be done by a machine, then what part of it was really me? i think that question is painful because it arrives at the same place. the original love. before the title, before the company, before the taste became a role, before the work became useful to other people, there was a small fire inside. curiosity. obsession. the feeling that the world became more alive when you understood a little more of it, or made a tiny piece of it bend to your will. AI can make the output faster. it can even raise the floor of the craft. but it cannot want on your behalf. it cannot decide what is worth loving. it cannot protect the strange private thread that made you care in the first place. maybe that is what becomes more important now. not whether you can still produce the artifact by hand. not whether you can outperform the machine at every task. that game is already changing. the real question is whether you still have a relationship with the source. the part with no audience. no roadmap. no deadline. the part that can wander, collect strange references, make useless things. follow beauty, be wrong, be slow, be you, be true. because that part is not separate from the work. it is the source of the work. if you lose it, you can still operate. you can still manage the machine. you can still prompt, review, decide, ship, and keep things moving. but the work becomes thinner. safer. more explainable. less alive. so maybe the real discipline is not to work harder, rest more, or care less. maybe it is to keep returning to the place where the love began – before it became useful, before it became legible, before anyone needed anything from it, before even the machine could mirror it back to you. not to escape the work. to make sure the fire inside is still alive.
