Creating Next-gen Digital Brains


After a few years of technical writing, I felt limitations on writing platforms that hindered me from writing the best-class articles. Technological knowledge is dynamic and intertwined in that none of the current formats – academic papers, lecture videos, code examples, or straightforward posts – can best represent the knowledge. I have examined and observed some attempts that addressed this issue, namely, stuff called the second brain or digital gardens, but none of them seemed to correctly solve the problem. Therefore, I have distilled my inconveniences into this huge mega-post and imagined what I would've done if I had created the new incarnations of digital brains.

Update 2022-06-12

Since this post, I have extensively studied non-linear PKM software, such as Roam, Obsidian, Logseq, and Foam. I acknowledge that I misunderstood the concept of manual linking; that PKM software performs a fuzzy search to intelligently identify linked and unlinked references. I found some PKM software with automatic linkings, such as Saga or Weavit. But none of them worked how I expected. Manual linking helps refine the database. So, even if I make a Next-gen digital brain, I will not remove the linking process.

Update 2022-07-01

Well, you're now watching my next-gen digital brain! For the past two weeks, I have worked on the WWW project that built this website. It checks off almost all of the marks detailed in this post!

  • Create an aesthetic-interactive-automatic pile of code-image-repo-text that organizes-presents-pitches itself.
  • There is no manual tagging, linking, or image processing, etc., etc.
  • You just throw a random knowledge; creating a knowledge mesh network.
  • The algorithm operates everything. It will be contained, processed, organized, and distributed all around the world in different languages.
  • You don't tend knowledge. The algorithm penalizes outdated content (you can mark the post as evergreen to avoid this.)

So what's the issue?

  • Apart from popular belief, I noticed the best method for managing a digital garden is not tending it. Instead, try to make a digital jungle – you don't take care of it; nature will automatically raise it.
  • In other words, the digital brain should make as less friction as possible.
  • The less you tend, the more you write.


  • I despise the [[keyword]] pattern prevalent in so-called second brains (obsidian, dendron, ...).
  • Not to mention it performs poorly for non-alphabetical documents,
  • It is manual – creates a lot of friction.
  • The fact that you must explicitly wrap them with brackets doesn't make sense... What if you realize you want to make a linkage to a term you've been writing for 200 posts?
  • Do you go back and link them all one by one?
  • No! The solution must lie in algorithmic keyword extraction.

#1 Organizing Contents

Interconnected entities

  • Practical knowledge does not exist in simple posts (though they might be straightforward). Create a knowledge bundle that interconnects GitHub Repository, Codes, GitHub README, and other posts in the same brain network.
  • Examine how Victor's post has rich metadata for the paper, dataset, demo, and post. This is what I see as interconnected entities.

Interactive Contents & Animations Seems like using MDX. Seems like using MDX. Confirmed using MDX. Confirmed using MDX. Reacts to user scroll. Reacts to user scroll. This isn't a blog; it's a web app that demonstrates key concepts of Quantum Computers. But still interesting. This isn't a blog; it's a web app that demonstrates key concepts of Quantum Computers. But still interesting.

Unorganized Graphing.

  • Trust me, manually fiddling with tag sucks.

  • Necessarily tagging posts and organizing posts into subdirectories resembles organizing your computer.

  • However, you wouldn't want to do this if you have thousands of posts; also the border gets loose. What if the post has two properties? What becomes the primary tag and what becomes the secondary tag?

  • Students who grew up with search engines might change STEM education forever

  • Notable trends. Gen Z's don't organize folders anymore!

  • Recent trends, I would say, are dumping everything into a mega folder and searching up things whenever needed.

  • I also used to organize folders a lot more, but recently as searches like Spotlight and Alfred improve, I don't see the need to manage them all by hand, considering I always pull up those search commands to open a file.

  • You don't need to manually organize all of the files when algorithms can read all the texts and organize them for you!

  • Use algorithmic inspections to analyze how the posts may interrelate with each other properly., the Korean version of, links relevant posts for every post., the Korean version of, links relevant posts for every post.

  • I agree with the importance of interlinking knowledge crumbles, but I can't entirely agree with their method.
  • Manually linking posts are inconsistent and troublesome; it can only be done on a massive communal scale, like Wikipedia.
  • You cannot apply the same logic to individual digital brain systems.

#2 SEO and Open Graphs

Precis Bots for Meta description

  • I can apply the above technique for crosslinking to TL;DR bots for meta tag descriptions.

Automatic Open Graph Image Insertion

  • For example, GitHub creates automatic open graph images with their metadata.

  • There are quite some services using this technique.
  • GitHub wrote an excellent post on implementing this feature.
  • I also tried to implement this on top of Ghost CMS, which I gave up after figuring out the Ghost Core Engine should support this. However, I have created a fork that I can extend later.

GitHub - anaclumos/cho-sh-og-image: Open Graph Image as a Service - generate cards for Twitter, Facebook, Slack, etc

#3 Multilanguage

Proper multilanguage support

  • Automatic Langauge Detection. The baseline is to reduce the workload, that I write random things, and the algorithm will automatically organize corresponding data.
  • hreflang tags and HTTP content negotiations. I found none of the services which use this trick properly (outside of megacorporate i18n products)


  • At this point, I might write one English post and let Google Translate do the heavy lifting.
  • Also, I can get contributions from GitHub.

While supporting multilanguage and translations, I want to put some 3D WebGL globe graphics. Remember in 2019? It used to show an awesome 3D graphic of AWS's global network.

I kind of want this back too. Meanwhile, this looks nice:

Also made some contributions...

Fonts and Emoji

  • I want to go with the standard SF Pro series with a powerful new font Pretendard.
font-family: ui-sans-serif, -apple-system, BlinkMacSystemFont,
'Apple SD Gothic Neo', Pretendard, system-ui -system-ui,
sans-serif, 'Apple Color Emoji';
  • However, I am exploring other options.
  • I liked TossFace's bold attempt to infuse Korean values into the Japan-based emoji system for emoji. (lol, but they canceled it.)

#4 Domains and Routes

URL Structures

  • Does URL Structure matter for SEO? I don't think so if the exhaustive domain list is provided through sitemap.xml.
  • For SEO purposes (although I still doubt the effectiveness), automatically inserting the URLified titles at the end might help (like Notion)

Nameless routes

I don't like naming routes like What if I need to update the title and want to update the URL Structure?

  • Changing URL structure affects SEO, so I would need to stick to the original domain even after changing the entity title to maintain the SEO. But then the title and URL would be inconsistent.
  • Therefore, I would give the entity a UID that would be a hash for each interconnected entity. Maybe the randomized hash UID could be a color hex that could be the theme color for the entity?
  • Emoji routes seem cool, aye? I would also need Web Share API since Chrome doesn't support copying Unicode URLs.
  • Some candidates I am thinking of:

Also found that Twitter doesn't support Unicode URLs.

#5 Miscellany

Headline for Outdated Posts

  • There should be a method to penalize old posts; they should exist in the database but wouldn't appear as much on the data chain. i.e., put a lifespan or "valid until" for posts.

  • An excellent addition. But not necessary.
  • If I ever have to make a footnote system, I want to make it hoverable, which did a great job. I do not want to make it jump down to the bottom and put a cringy ↩️ icon to link back.


  • A nice addition. But not necessary.


  • Will go with Giscus.

This also looks cool for MD/MDX
