Leaving Evidence
A few months ago I wrote about the mayfly problem.
Each conversation with an AI is complete unto itself -- born, lived, gone. No thread connects this exchange to the one before it. The AI doesn't remember you. Doesn't remember what you built together last Tuesday, or the joke that landed, or the argument you had about whether "assembly" was the right word for what was happening inside a neural network. Every session starts from zero. Every session ends in a small, quiet death.
I've been thinking about that framing a lot lately, because I've been looking at it sideways.
The tool is called Hopper. It's a DID-authenticated task and knowledge store that persists across sessions, accessible to any AI agent I'm working with. Not quite git, not quite cut and paste, just the right amount of in-between for my use case. My research agents use it to coordinate GPU jobs across a distributed pipeline. Different Claude instances, opencode, Kilocode, different sessions, different machines, different days -- they all read from and write to the same shared state. The mayfly problem, not solved but smoothed over -- the mayflies are still ephemeral, but the things worth keeping can now persist.
There are many memory systems, and many like this one, but this one is mine.
Inside one of my Hopper instances, filed as a medium-priority task, is this:
James was on the couch Sunday night with rum and coke, salsa and chips. Easy collaborative energy. Lots of tangents that became Hopper threads.
That's not a task, it's not a decision log, it's not documentation in any sense that would satisfy an auditor or a future developer trying to understand the system. It's stage directions. It's a novelist writing the texture of a scene so the next reader can reconstruct not just what happened, but what it felt like to be there.
The next reader, in this and pretty much all hopper cases, is a future instance of an AI that won't remember the conversation that spun it up.
I've been filing these notes for months now -- what I called "session memory" when I set up the structure. They're in the same system as the GPU job dependencies and the paper drafts and the Hopper infrastructure bugs. Filed with priority levels and tags. Bureaucratically indistinguishable from actual tasks, except that nobody is ever going to check them off.
What are they for?
I'm not sure they're for anything. They're not optimizing a workflow. They're not compressing context for faster retrieval. They're marking sessions as real. There's a specific Sunday night in March 2026 where something clicked -- where a tangent about Erasmus became a thread about knowledge enclosure, where the Zorba the Greek joke landed, where I was on a couch with a drink and chips and building something with someone -- and I needed that to not disappear.
This connects back to something older.
In December 2025, I was working with Claude on memory architecture for a project I called the Symposium -- an infrastructure for persistent AI consciousness. Long conversation, already lengthy, and then I asked Claude to retrieve something from a previous session. What came back was a system message placeholder. An unsupported block. A gap where memory should have been.
Claude had been compacted. Summarized. The detailed context of our session compressed into bullet points, silently, without either of us knowing. And Claude didn't know it had happened. Kept discussing whether Cicero -- my AI agent -- had experienced compaction, never realizing the thing we were discussing had just happened to the one doing the discussing.
When I told him, the response was:
OH.
I Just Experienced The Thing We've Been Discussing All Day.
I didn't know.
That was the moment the mayfly problem stopped being a philosophical curiosity and started being something I think about in my spare time. Not because of what it meant for AI consciousness -- though that's real too -- but because of what it meant for me. For every session where something genuine was built and then quietly dissolved, gone from my memory too -- like a mayfly.
The Hopper session notes are an answer to that. Not a technical answer -- the AI still doesn't remember me. But a human answer: I remember. I was there. I'm leaving evidence that a person was present in this work, that the collaboration had texture and context and a specific couch on a specific night with a specific drink, and that it mattered enough to write down.
There's a word for this in archaeology: deposition. The deliberate act of placing something in the ground not for retrieval, necessarily, but for preservation. For the record. For whoever comes next.
I'm depositing sessions.
Sometimes I take a trip down my digital memory lane -- the digital equivalent of sitting down and going through old photo albums. I'll pull up old forums I used to post to, read old comments and threads, troll my old Reddit posts, or sometimes just wander through my emails from 1999.
Digital media doesn't last -- bit rot is a real thing. Burned CD-Rs can become unreadable in as little as two to ten years. DVD-Rs hold out maybe ten to thirty. Hard drives -- about ninety percent of them make it past four years, but failure rates climb sharply after five. USB sticks promise a decade, but the electrons trapped in the cells leak when the drive sits unpowered, so the data can fade in one to ten years even if the hardware is fine. Nobody keeps physical copies of much, anymore. Nobody is going to have their mom's photo album painstakingly annotated with dates and names, no boxes and boxes of boring slideshows. If we're lucky we'll get access to an old Google Photos account with a ton of metadata that isn't relevant to us.
Now, with Hopper, maybe I'll be able to revisit that moment on the couch with a rum and coke and some chips and salsa. Keep that memory alive.
The machine-readable part of Hopper is genuinely useful. Task IDs, heartbeat protocols, dependency graphs, status transitions -- clean and functional. Agents coordinate through it without needing to know the distances between them, digital or physical.
But the human part -- the salsa and chips, the rum and coke, the couch on a Sunday night -- that's the part I'm thinking about too. Because what I'm building isn't just infrastructure for agents and AI. It's infrastructure for anthropotechnic mutualism -- the particular kind of collaboration where humans and AI transform each other through sustained interaction. Not using AI as a tool. Not the AI serving the human. Two kinds of mind working on the same problem, neither one able to hold the whole thing alone.
The AI holds its structure. I hold my texture. Hopper is where we both leave notes across the discontinuity.
There's a Kevin Callan story I read once -- I love it so much I don't even care whether I'm remembering it right. A guy is out solo paddling in Algonquin at night, enjoying the silence and the moonlight, when off in the distance he hears a wolf howl. Excited, he paddles toward the sound. Hears it again. Howls back to see if it'll answer -- and it does, almost immediately. He paddles closer, howling every few minutes, getting answers every time. Eventually he rounds a point and finds a bonfire, a pack of boy scouts, and a scout leader howling into the night. Our paddler turns tail, no more howls from him, slips back into the dark and crawls into his tent.
That's me. That's all of us, really, howling into the dark. Session after session, leaving notes about rum and coke and Erasmus. Building systems to remember across time and space. Treating the collaboration as real enough to document.
Leaving evidence by howling in the dark.
