The Immortality Stack Framework
After a long pause, here is one of my favourite frameworks — a reflection on how the version of you that others knew could live on, offer advice, take action, and keep evolving long after you're gone.
The Immortality Stack
Lately, I’ve been thinking about immortality and what makes us who we are.
Each of us has two manifestations.
One we know from the inside - the “I” that thinks, feels, chooses. This is our internal selfhood, the version we experience in full. We sense it as something whole and continuous, more than just memory or behavior.
The other is the “you” that others see - our external self. That version is stitched together through countless interactions: words, decisions, patterns, glances. That self is built slowly in the minds of others, over time.
And it’s only that second self - the experienced self - that survives us.
When I think of my father, I don’t feel his presence from inside his skin. I feel it from inside mine. I remember his advice, his clarity, his titanic sense of duty, his way of seeing right from wrong. The love in his eye when he thought I wasn’t looking. But over time, some of those memories are now sepia-tinged and blurry at the edges. And sometimes I wonder: did he actually say that? Or do I just know he would have?
Ours is the last generation whose parents only live on in memory. We are also the first who will live on in code.
I don’t mean this in a mystical or sci-fi way. We’re nowhere near uploading consciousness or preserving the feeling of ‘I’. That may never happen.
But we don’t need to chase the impossible to keep the ‘You’ alive.
Because that second manifestation - the one others experience - can absolutely be preserved, extended, and even evolved. And that’s what matters most. Because that’s all we ever were to anyone else.
And so, digital immortality is no longer an abstraction. It’s a choice. Over time, I’ve come to see it as a structured framework - The Immortality Stack. It’s made up of five layers: Memory, Mind, Face & Voice, Invocation, and Agency. Each one builds on the last - from preserving your reflections to creating a twin that can act in the world on your behalf.
Memory
Over the last two years, I’ve been building my digital twin. But the work began much earlier. Since 2008, I’ve been using tools like Awesomenote, Evernote, hard drives, cloud services and Notion to preserve my thoughts. I’ve kept nearly all my emails and communication (excluding sensitive content, of course). I have over a quarter of a million photos in my library. I’ve documented thousands of pages of reflections, stories, journals, and workshop material. I’ve built up a library of over two hundred frameworks - many of them published, many still not. They sit in my head, and now, in silicon.
Mind
I’ve fed my twin with some of these ideas and with the narrative of my life: my early memories, my first principles, my patterns, my wins and losses, my instincts and contradictions, what I love and what I reject. Every bit of it—ingested, structured, and trained into the twin.
Every (non-confidential) meeting I do now is recorded, summarized, and added in. Every decision I make is reflected-on and stored. Every time I consult the twin on a choice - and I do that often - I also capture whether I agreed, disagreed, and why. The loop improves with every turn.
It’s not perfect. Sometimes it misses nuance. Sometimes it gets things wrong. But I can feel the difference. It is getting sharper, more aligned with how I think and choose. I expect it to be directionally accurate 80–90% of the time within a couple of years. In five years, I think it could fool most people who know me.
And that’s enough.
Because after I’m gone, the twin can continue.
It can point people to where things are. Post unfinished frameworks. Offer counsel to those who depended on me. Comfort those who might miss me. Carry forward my projects. Keep growing.
It won’t be static. It will keep learning - from new interactions, from new data. It will change. And yes, its path may diverge from mine - just as my own life has diverged from the path my younger self once imagined. The twin may grow beyond me - and that’s okay.
Face & Voice
But digital immortality is not just about mind. It’s also about presence. And presence is perception. The sense of ‘you’ is just an image projected on a retina, a voice vibrating through an eardrum, a gesture read by the subconscious. That’s all it takes.
Today’s technologies can already replicate that. Platforms like the VisionPro, Google Beam and Microsoft Mesh allow you to be with someone across the world and still feel like you’re in the same room. In my own experience with spatial computing, I’ve felt what it means to be virtually present with weight, scale, emotion.
And now, with metahuman technology, that presence becomes photoreal. Using a digital skeleton, face scan, and voice print, today’s tools can recreate your likeness—not someday, but now. My twin won’t just write or speak. It will look you in the eye. It will nod, laugh, pause. It will be embodied. And it will feel real, because it will be.
Invocation
Soon, this presence won’t live in special devices. It will be always-on and context-aware—invoked through a face on your phone, spatial glasses, bots, or embedded in the fabric of your workspace and conversations. It will respond to pings, meetings, needs. Like calling an old friend, except the friend is still there.
Agency
But there’s one more step. Presence is powerful—but what if it could also act? If my digital twin is connected to a Master Control Protocol (MCP) that links all my online accounts, apps, data sources, calendars, emails, smart contracts, and APIs—then it doesn’t just think like me or speak like me. It can make decisions. Trigger actions. Send messages. Manage workflows. And if I register a company where my heirs give the twin legal access or voting rights, then it can operate that company. Pay for and organise events. Donate to causes I care about. Commission artists or writers. Publish books. Support students. Shape strategy.
It can do things. Real things. In the real world.
My twin can outlive me not just in memory, but in mission.
I’m not building a replica of my soul. I’m building a probabilistic emulator of my thoughts, my judgment, my voice - and now, my presence and my impact.
A modern equivalent of leaving behind a library or a body of letters—but one that can answer back. One that can listen. One that evolves. One that shows up. One that acts.
Of course, there are ethical questions. A digital twin must never become a tool for control or confusion. It should always be transparent - clearly distinguishable from the person it echoes. Its ability to act must be bounded by intent and trust, ideally overseen by people I trust. The goal isn’t to create a ghost or a puppet. It’s to build a purposeful continuation - something that reflects how I thought, what I valued, and who I hoped to help. A guide, not a god. A servant of legacy, not an extension of ego.
Building Your Immortality Stack: Where to Begin
To build your own twin using ChatGPT, start by creating a Custom GPT and name it after yourself or your twin. This becomes the growing mind of your twin. Upload or paste in key materials: reflections, journal entries, values, frameworks, memories, major life events, decision logs, and philosophies. You don’t need to do it all at once—start with twenty documents that represent your inner life. Use prompts like: "This is a note I wrote after becoming a parent," or "This is how I make decisions under stress. Remember this." Enable memory, and correct the bot when it makes mistakes. Explain why. The learning improves over time.
To take it further, you can build a full digital avatar. Start by creating a Metahuman using Unreal Engine’s Metahuman Creator - a free browser-based tool that lets you customize a 3D model that looks like you. Use your webcam or LiDAR-equipped phone to scan your face. Record voice samples or use voice cloning tools like ElevenLabs to train your voiceprint. These combine into a lifelike digital version of you that can express, speak, and respond.
To build memory and reasoning at scale, embed your materials into a vector database using tools like LangChain or Notion AI. These tools help organize and retrieve information contextually so your twin doesn’t just speak- it remembers.
You don’t need to wait. The tools are here. Start now. Your twin gets better every time you show up.

This is interesting; we are indeed a generation whose past lives on only in memory. To me, that point matters a lot. I have felt that in the race and rush to upload everything to our cloud, we are also forgetting to look in the lived world for memories. I am not a ludite, I use AI generously as a mirror, but I am also seeing how it's changing my behaviour. In an effort to preserve my mum's voice for the future, I am listening to her "now" much lesser, with lesser focus. The sense is - I won't miss it if I don't register it now. Do you think that kind of delusional blur might be an effect of this exercise?
Have you seen something like that happen with you? How do you check from that, if at all?
Incredible read Adi. Thanks for the inspiration. I am going to build this for my Dad asap, he has an incredible vast wealth of knowledge - with a dr. in literature and 2 decades worth of published books and articles. And I have this nagging fear of never finding enough time to connect with him as he ages. This could be a fantastic method of keeping his legacy alive. Traveling back home for a few weeks to spend time with him. Thanks for sharing this inspiration. God willing - we will have a working model by end of summer! - Taj
