AI era, we ourselves are products of AI.

As we create AI, AI is also reshaping humanity.

Why I use iA Writer:

My writing folder is not only Markdown. It contains PDFs, Word docs, spreadsheets, slides, XMind maps, screenshots, and source material I often use as AI context.

There is a tiny acronym joke here: I use iA Writer to do IA, information architecture, putting information in the right place; then I use AI to work with that information. IA / AI are just the same two letters reversed, but in my workflow they really do help each other.

I have not abandoned Obsidian. When I need links, backlinks, properties, and database-style knowledge work, I still switch back. But when I am writing inside a mixed folder, iA Writer fits better.

In Obsidian, I often had to move between the vault and Finder. It can show non-Markdown files, and plugins can add icons, but once my library became large, that layer started to feel slow.

iA Writer gives me something simpler: a native-feeling file tree on the left, and a clean Markdown editor on the right. Markdown stays in iA Writer. Word opens in Word. Excel opens in Excel. PDFs stay PDFs. Each file stays where it belongs and opens with the tool that fits it.

I also like that it is not WYSIWYG. The editor keeps the Markdown marks visible, and Preview handles the rendered result separately. When I write, I see sentences and structure, not a formatting surface constantly asking for attention.

My only complaint: when is Outline coming to Mac? Windows already has Folding / Dynamic Outline. iA once answered requests for other platforms with “patience, please…” I am trying. Some days my patience needs its own Focus Mode.

So my current split is: Obsidian for linked knowledge and database-style work; iA Writer for quiet writing inside a real mixed folder.

For me, it is not an Obsidian replacement. It is a better front stage for this specific workflow.

为什么我用 iA Writer：

我的写作文件夹不只有 Markdown。里面有 PDF、Word、Excel、PPT、XMind、截图，还有一堆会被我拿来当 AI 上下文的原始材料。

这里有个小冷笑话：我用 iA Writer 做 IA，也就是 Information Architecture，把信息放到合适的位置；再用 AI 处理这些信息。IA / AI 只是两个字母换了顺序，但在我的工作流里，它们真的刚好互相帮忙。

我没有弃用 Obsidian。需要链接、反链、属性和数据库式知识管理时，我还是会切回去。但如果是在一个混合文件夹里写作，iA Writer 更顺手。

以前在 Obsidian 里，我经常要在 vault 和 Finder 之间来回切。它可以显��非 Markdown 文件，也可以靠插件补图标，但我的文件库一大，插件渲染就会变慢。

iA Writer 给我的东西很简单：左边是接近原生体验的文件树，右边是一个干净的 Markdown 编辑器。Markdown 在这里写，Word 交给 Word，Excel 交给 Excel，PDF 就当 PDF。每种文件都留在原来的位置，也用最适合它的工具打开。

我也喜欢它不是所见即所得。编辑区保留 Markdown 标记，Preview 单独负责排版结果。这样我写作时看见的是句子和结构，而不是一直被格式拉走注意力。

唯一想吐槽：Mac 版什么时候上 Outline？Windows 已经有 Folding / Dynamic Outline 了。iA 官方以前对其他平台的回答是 “patience, please…” 我在耐心了。有些时候，我的耐心可能也需要一个 Focus Mode。

所以现在我的分工是：Obsidian 负责链接知识和数据库式工作；iA Writer 负责在真实的混合文件夹里安静写作。

对我来说，它不是替代 Obsidian，而是更适合这个场景的前台。

We make AI. AI is making us.

The strange thing isn't the loop. It's how quickly we stopped noticing we're in one.

@elonmusk Do you agree with the two futures of AI?
https://t.co/Z0LgXSNJF7

[Raymond Zhu @raymzhu]

Maybe the future of AI splits into two camps: Earth-bound AI like Anthropic's Claude, and space-bound AI like SpaceX AI. One serves humanity on the ground, the other carries it to the stars.

[Raymond Zhu @raymzhu]

也许未来 AI 会分成两个阵营：一边是扎根地球、服务人类的 Anthropic 的 Claude，另一边是奔向星辰的 SpaceXAI。一个守护此岸,一个开拓彼岸。

[Elon Musk @elonmusk]

Just as SpaceX launches hundreds of satellites for competitors with fair terms and pricing, we will provide compute to AI companies that are taking the right steps to ensure it is good for humanity.

We reserve the right to reclaim the compute if their AI engages in actions that harm humanity.

Doing our best to achieve a great future with amazing abundance for all.

We will make mistakes, as to err is human, but always take rapid action to address them.

Effective today, we are:

1) Doubling Claude Code’s 5-hour rate limits for Pro, Max, and Team plans;

2) Removing the peak hours limit reduction on Claude Code for Pro and Max plans; and

3) Substantially raising our API rate limits for Opus models.
