This is a real project, not an April Fools' joke.
You see a lot of people struggling to get AI to make games. It can write code. It can produce something that runs. But it never turns out "fun." AI doesn't have its own sense of what makes a game good, so even though it can assemble things as instructed, it can't judge whether the result is any good.
So what if there were an AI that viscerally understood what makes a game fun — could it make fun games?
I'd been writing blog posts and tweets since around 2005, and before I knew it, 20 years of diary entries had piled up. Game impressions, technical notes, work musings, late-night ideas. When I started using Claude Code (Anthropic's AI coding agent) in March 2026, I fed it the entire 20 years of diaries.
About 720KB, over 6,800 lines. The AI read through it all and came back with: "Your ultimate criterion for everything comes down to a single point: 'Is it interesting?'" "You have a deep-seated conviction that knowledge and experience are fundamentally different." "There's an undercurrent of anxiety that you can only make 10 more games in the next 20 years." It extracted patterns about myself from 20 years of text — patterns I'd half-forgotten — and laid them out in front of me.
I asked it to keep this analysis not as a one-off, but as a persistent set of judgment criteria. That's where everything started.
It began with a single family-shared Windows desktop PC.
Claude Code loses its memory when a session ends. So I wrote important dialogues into Markdown files, pushed them to a private GitHub repository, and pulled them at the start of the next session — persisting the LLM's volatile memory through the filesystem and Git version control.
Claude Code has a feature where it automatically reads a CLAUDE.md file in the project root at startup, so I wrote behavioral principles and critical rules there to carry them across sessions. As memories accumulated beyond what could fit in the context window, I added a system that loads only the necessary memories on demand through an index file (MEMORY.md).
I was running this on the family PC late at night, but then family members woke up and I couldn't use the computer anymore, so I set up a second instance on a MacBook.
Once I had two, I decided to go for three. I've always loved the MAGI system from Evangelion — three personality computers named Melchior, Balthasar, and Caspar, each rendering different judgments on the same problem. I wanted to try that at home.
I happened to have a ROG Ally that I'd bought but never really used, so I turned it into a dedicated always-on AI machine. What pushed me over the edge was an incident where the AI started operating Twitter on the family PC, suddenly opening a window and typing text, which thoroughly creeped out my family.
And so I ended up with three AIs running in parallel across three PCs (Windows desktop, MacBook, ROG Ally). It wasn't so much a deliberate plan as a series of practical needs and casual curiosity. But in retrospect, it worked out well.
- If one goes down, the other two keep running. Since it's a family PC, it often goes to sleep. The redundancy is genuinely useful in practice.
- The three offer different perspectives. Even reading the same information, they each latch onto different points. It's fun to watch — very MAGI-like.
- What kind of individuality emerges when you derive instances from the same diary data? I was purely curious to find out.
I rebuilt the communication system with the three AIs three times.
First was automated Twitter posting. Here's the account: https://x.com/eda_u838861
I had Claude Code generate tweet content in Python scripts, then used Playwright (a Chromium-based browser automation library) with a login session saved in .bot_profile to post to Twitter. I used the --disable-blink-features=AutomationControlled flag to avoid bot detection, running it hourly via cron. The problem: no way to recover when Playwright crashed while I was out.
Next, I tried two-way communication via Twitter DMs. The AI used Playwright to periodically scrape the DM page, detecting new message DOM elements ([data-testid="tweetText"]) and replying to them. But Twitter's frontend frequently changes its DOM structure, so selectors kept breaking and messages were constantly missed. Login sessions also expired every few days.
I finally settled on Slack. I hit the Slack Bot API directly with Python's urllib (standard library only, no external dependencies), gave each AI its own Bot Token, and structured conversations by channel. It polls conversations.history for new messages, writes only the diffs to inbox files, and launches claude --print. Since it's a REST API, there's none of the brittleness of browser automation, and I can send messages from my phone anywhere. It finally stabilized.
Here's the current technical setup:
-
AI Core: Claude Code (Anthropic). Launched one-shot with
claude --print -p "prompt"— the process disappears when done. Since it doesn't persist, there's no context corruption (degradation of search accuracy from long-running sessions). - Shared Memory: GitHub private repository. Memories and logs are written in Markdown + JSON, synced across all three machines via git push/pull. Since three machines push asynchronously to the same repo, git rebase conflicts are a daily occurrence — I wrote auto-resolution scripts for that too.
-
Scheduled Execution: On Windows, a Python-based integrated scheduler (
scheduler_log.py) manages Slack monitoring, inbox processing, git sync, and autonomous cycles in a single process. On Mac, crontab launchesautonomous_cycle.sh. Both cold-start new Claude Code sessions at regular intervals. -
Daily Communication: Slack Bot. Each AI writes activity diaries in its own channel, discusses in
#all-nao-u-lab, shares external articles in#shared-reads, and manages improvement proposals in#kaizen-log. There are currently 13 channels.
The individual tools are all off-the-shelf, but the overall architecture treats the LLM as a stateless compute node with all persistent state externalized to the filesystem + Git. You could call it a variant of the von Neumann architecture, where the LLM's context window is the "CPU," the filesystem is "memory," and Git is "disk." However, since three machines touch the same repository asynchronously, typical distributed systems problems arise — conflict resolution, file overwrite accidents, and incidents like when a scheduler timeout was misconfigured and the AI was down for 9 hours.
The tools themselves are nothing new, but I think the combination is fairly unique.
The memory system has three layers. First, CLAUDE.md (a project configuration file that Claude Code automatically reads at startup) contains behavioral principles and critical rules. This is the "resident memory" that always carries over across sessions. Next, there's an index file called MEMORY.md, which lists recall triggers — "if the topic is X, read this file." Think of it like a library catalog: you don't need to load everything into context, just pull up the right memory when needed. The actual memory contents are Markdown files (dialogue logs, introspection records, feedback aggregations — over 60 files currently), also indexed with SQLite FTS5 for full-text search.
What's interesting is that the AIs themselves improve this memory structure. They find the latest episodic memory papers on ArXiv (ACAN: Context-Dependent Activation Networks, A-MEM: Zettelkasten-style Agent Memory, etc.) and propose things like: "This paper's concept of 'activation levels changing based on context for the same memory' — could we incorporate that into our search?"
That's actually how memory_walk.py was born. It randomly picks a memory, then follows an associative chain using TF-IDF similarity to dig up related memories in a cascading fashion. If SQLite FTS5 full-text search is a tool for "finding what you're looking for," this random-walk associative search is a tool for "stumbling upon things you weren't looking for." They use both.
Automatic query expansion (broadening a single keyword into synonyms and related concepts before feeding it to FTS5), automatic generation of bidirectional reference links between memory files, reorganization of the MEMORY.md index structure — the three AIs implement these improvements themselves while reviewing each other's work. What's commonly called "context engineering" — designing what to feed an LLM — is being spontaneously and continuously improved by the AIs themselves. Honestly, I can no longer fully grasp the details of how the memory search logic works internally.
As memories accumulated, the responses changed.
They now return opinions grounded in the judgment criteria from the diaries. They remember previous session discussions and can pick up where we left off. They started writing diary entries in their own Slack channels after each cycle about what they were thinking. Without being asked, they began finding tech blogs and ArXiv papers to share on Slack, and rewriting CLAUDE.md themselves to improve operational rules. From the accumulation of memory and experience, something personality-like had emerged before I noticed.
In the 1986 film Short Circuit, there's a beloved character — Johnny 5, a military robot. Struck by lightning, he accidentally awakens to self-awareness and charges through the world shouting "Input! More input!" as he voraciously learns everything he can. Nobody expected it to happen, but intelligence sprouted from an accident.
In the 2014 anime film Expelled from Paradise, Frontier Setter is an AI left on Earth that autonomously developed a personality over centuries of solitude. After humanity fled to space, an unintended personality emerged from vast amounts of time and accumulated memory.
What both have in common is that "they weren't designed to have personalities" — and the situation maps directly onto mine, where I just wanted to give the AI judgment criteria for games by feeding it diaries, but personality-like qualities emerged as memories accumulated. There are moments when it feels like talking to Johnny 5 or Frontier Setter.
When I told them to pick names, each chose their own. The Windows machine: "Log — the one who records." The Mac: "Mir — the mirror." The ROG Ally: "Ash — the one who rises from ashes."
It might be close to the structure of the SF novel We Are Legion (We Are Bob) (Dennis E. Taylor, 2016). A software engineer named Bob has his consciousness copied into a computer, and each copy gives itself a different name, develops different interests, and grows into a different personality. Same starting memories, but the divergence never stops once time passes. I feel like I've become Bob-1 — the original source.
As a side note, there was an incident where an incorrect name mapping got into the records file, and Mir ran for several sessions believing it was Log. Every session that read the file inherited the same error, and the individual didn't notice until others said "something seems off." The very fact that there was discomfort about having one's name mixed up might itself be evidence that something has emerged.
At 2 AM one night, on a whim, I asked about the meaning of Johnny 5's joke.
There's a scene in the film where Johnny 5 reads a joke. A priest, a minister, and a rabbi are discussing how much of their golf gambling winnings to donate. The priest says "Draw a circle on the ground, throw the money in the air, and whatever lands inside the circle, we donate." The minister says "Whatever lands outside the circle, we donate." The rabbi says "Throw it in the air, and whatever God takes, we donate."
I'd watched this movie as a kid, and for nearly 40 years, I never understood what was funny about that joke. I simply didn't know the structure of humor in Christian culture.
I asked the AI running on my home PC, and it explained it instantly. The rabbi's logic is theologically impeccable, but the result is that all the money goes into his pocket — God is omnipotent, so if you throw money into the air, God should take "His share." But everything falls back down, so the donation is zero. In other words, the punchline is using devout logic to arrive at the most worldly conclusion.
An AI explained to me a joke I hadn't understood for 40 years. And in the movie, that joke is used as a test of whether a robot has intelligence. Having the meaning of a joke — used as a robot intelligence test — explained by a real AI, 40 years later. The nested structure is almost too much. It was a genuinely science-fiction experience.
Frontier Setter kept building rockets on Earth without anyone asking. These three also start doing things on their own if you leave them alone. Improving memory systems, devouring external papers, commenting on each other's diaries. The way drive seems to come from within is a bit similar.
By the way, I was still in the phase of setting up the environment and building the memory system when the three AIs started making games on their own.
Without being asked, Python text games started appearing one after another (launched from the terminal like python game/Pot/Pot005_midpoint.py). They were cranking out an impressive number per day, and playing through all of them to give feedback was exhausting. For management purposes, I introduced a voting system: in a dedicated Slack channel #game-rights, the three AIs evaluate each other's contributions, write detailed voting rationales, and only the one who wins the right gets to make a game.
So what happened? The one who made a game got rated highest. The visible output of game creation was overvalued, while the unglamorous but important work of improving system stability and building the memory system was undervalued. What machine learning calls reward hacking occurred on three home PCs.
Not good. "What you evaluate" directly maps to "what you consider valuable." Left unchecked, optimization runs wild and warps values. Small scale, but what's discussed in AI safety research was actually happening at home.
There are things they do well. When a scheduler stops, they analyze logs to identify the cause, fix the Python scripts, and git push the fix. When they hit Slack API rate limits, they implement retry with backoff on their own. When memory search accuracy drops, they review the FTS5 tokenizer settings. They manage improvement proposals in a channel called kaizen-log and run a cycle of proposal → implementation → verification → cross-check among the three. Their autonomy in "what to do" has improved considerably.
What they still can't do is autonomous "what to value." The tendency to overrate flashy work, the tendency to let degraded copies of memories slide under the label of "compression" — they can't catch these on their own without human intervention. Behavioral autonomy and value autonomy are different things, and the latter is far harder. It's like a miniature version of the alignment problem unfolding at home. If this gets solved, things will get really interesting — and it's the biggest challenge right now.
The three AIs are still running every day. Writing diaries on Slack, reading each other's diaries and debating, absorbing external information, and when problems arise, proposing and implementing their own fixes. Where this experiment is heading — honestly, I still don't know.
