你好，星際的朋友。
今天上午，一位住在華為市的大一學長找我開會。
我國一的時候，就在技術社群裡認識他了。那時候，他已經在做一些很誇張的東西，例如把舊家具掃描成可修改的模型，再用 AI 補齊損壞或缺失的部分。
現在，他真的做出產品了。
使用者可以掃描生活中的杯子、桌燈、收納架之類的小東西，系統會生成可修改、可分享，也能直接用於製作的模型。他甚至已經架好了伺服器和基本網站。
我本來以為，他找我是要問模型、協議，或網站架構的問題。
結果他說，他不知道該怎麼進入歐美市場。
不是技術做不出來。
而是做完之後，他才發現世界上已經有很多扇門，而每一扇門都有人守著。
大型平台可以帶來流量，但使用者必須使用指定帳號、指定支付方式和指定的推薦系統；使用者資料得回傳，曝光規則由平台決定，抽成比例也可能隨時改變。
我問他：
「如果你明天離開這些平台，你能帶走什麼？」
他想了一下。
程式碼可以帶走。
模型可以帶走。
伺服器可以帶走。
產品資料大部分也可以帶走。
但他帶不走使用者。
帶不走評價。
也帶不走那些曾經透過平台認識他，卻不知道他的真正網站在哪裡的人。
如果平台把他的產品排到最後面，他可以重新投放廣告。
但如果他不想付錢，可能就沒有人看得到。
昨天做《星際關係概論》作業時，我聽一位外星研究員說：真正的自由，不是可以離開一套規則，而是離開時不必被迫從零開始。
當時我想的是人。
一個人離開原本的城市、學校、工作或制度時，能不能帶走自己的學習紀錄、醫療資料、技能證明、資產，以及重新開始的機會？
今天，我看到了另一種版本。
產品和人當然不能直接放在一起比較。但它們都碰到同一個問題：如果你所有累積的關係、信任和入口，都被鎖在別人的系統裡，你表面上可以離開，實際上卻很難真正離開。
真正握有權力的人，不一定是命令你加入的人。
有時候，是那個能決定你離開之後還剩下什麼的人。
我沒有立刻答應幫學長做網站。
我只跟他說，先不要急著問該怎麼走進歐美市場。
先列出來：如果明天必須離開任何一個平台，什麼東西最不能失去？
那些東西，才應該先放在自己手裡。
今天先記到這裡。
Hello, friends among the stars.
This morning, a university senior who lives in Huawei City asked me to meet with him.
I first met him in a technology community when I was in seventh grade. Even then, he was already building some remarkable things, such as scanning old furniture into editable models and using AI to complete damaged or missing parts.
Now he has actually turned it into a product.
Users can scan small objects from everyday life—cups, desk lamps, storage racks, and things like that. The system generates models that can be edited, shared, and used directly for manufacturing. He has even set up the server and a basic website.
I originally thought he wanted to ask me about models, protocols, or website architecture.
It turned out that he did not know how to enter the European and American markets.
It was not because the technology was beyond him.
It was because, after finishing the product, he discovered that the world already had many doors, and every door had someone guarding it.
Large platforms can bring traffic, but users have to use designated accounts, designated payment methods, and designated recommendation systems. User data has to be sent back. The platform decides the rules for visibility, and the commission rate can change at any time.
I asked him:
“If you left these platforms tomorrow, what could you take with you?”
He thought for a moment.
He could take the code.
He could take the models.
He could take the server.
He could take most of the product data.
But he could not take the users.
He could not take the reviews.
He could not take the people who had once discovered him through the platform but did not know where his actual website was.
If the platform pushed his product to the bottom of the list, he could buy advertisements again.
But if he did not want to pay, perhaps no one would be able to see it.
Yesterday, while working on our assignment for An Introduction to Interstellar Relations, I heard an alien researcher say: True freedom is not being able to leave a set of rules. It is not being forced to start from zero when you leave.
At the time, I was thinking about people.
When someone leaves their original city, school, job, or system, can they take their educational records, medical data, skill certifications, assets, and the chance to start over with them?
Today, I saw another version of the same question.
Products and people obviously cannot be compared directly. But they encounter the same problem: if all the relationships, trust, and points of entry you have accumulated are locked inside someone else’s system, you may appear to be able to leave, while in reality it is very difficult to truly do so.
The people who hold real power are not always the ones who order you to join.
Sometimes, they are the ones who can decide what you have left after you leave.
I did not immediately agree to build a website for my senior.
I only told him not to rush into asking how to enter the European and American markets.
First, make a list: if you had to leave any platform tomorrow, what would be the one thing you could not afford to lose?
Those are the things that should be kept in your own hands first.
I will stop here for today.
