Only You Were There

The Ethical Legacy Will in the age of AI

My grandparents kept a giant breakfront in their dining room — porcelain figurines lined up behind curved glass, the kind of furniture that felt like a museum you weren’t supposed to touch. But the real treasure was a secret only my grandfather knew. He’d call my brother and me over, open the top right drawer, and produce a box of eight campfire marshmallows, as if they’d been sitting there waiting just for us.

As I got older, I got bolder. I snuck back to that drawer on my own to grab one for myself — and found it empty. I was certain he’d put the box back. But somehow, every single time, the marshmallows had disappeared. I never worked up the nerve to ask him how the trick was done. I’m about the age now that he was then, and I think I’ve finally figured it out.

He wasn’t doing magic. He was quietly restocking that drawer, over and over, year after year, so that two boys would keep believing in a small miracle. Nobody else was in that room making that choice, again and again, to keep the secret going. Only he was there.

Jewish law has a demanding, almost severe, standard for testimony. An eid — a witness — may only testify to what they themselves saw, at the moment it happened. Eidut mipi eid, testimony passed from the mouth of one witness into the mouth of another, generally isn’t admissible. Hearsay doesn’t count, no matter how detailed, no matter how sincere the person repeating it. The law insists on this because it understands something true about experience: there is a categorical difference between having been there and having been told about it.

An AI trained on your emails, your voicemails, your old home videos, can produce something that sounds remarkably like you. It could probably even describe a drawer full of marshmallows. What it cannot do is testify. It was never there. It has no eidut to give — only a very convincing echo of one.

This is why my fondest memory of my grandfather isn’t really the marshmallows. It’s the choice underneath them — the private decision, repeated for years, to let a small joy cost him some effort so that it would look effortless to us. Deciding what a moment should feel like, and then quietly making it feel that way, isn’t data. It can’t be reconstructed from a photograph of a breakfront or a story about a drawer. It can only be given, person to person, by someone who actually made the choice, and chose you to receive it.

This is not a temporary limitation, waiting on the next model. It is a permanent one. However good the mimicry gets, mimicry is not testimony. A pattern is not a witness.

For as long as I’ve been doing this work, the case for the Ethical Legacy Will has been the ordinary, sufficient case: don’t wait. Say the things that matter while you’re still here to be asked the follow-up question. That case hasn’t changed. But it now sits inside a harder deadline than it used to. Increasingly, the people you love will have the option of manufacturing a version of you that talks like you, if they miss you enough and the technology is convincing enough. They should never have to settle for that. And the only way they don’t have to is if you give them the real thing first — while you’re the only one who can. I still hope, someday, to fill a drawer of my own for a grandchild, and let them wonder how the trick is done. That beautiful breakfront serves as a bookcase now, a beloved piece of me that sits behind my desk in my study.

So the question isn’t only what you want them to remember. It’s this: are you willing to let your grandchildren’s only account of you be secondhand, assembled by a machine that was never in the room? Or will you have been the one who was actually there — filling the drawer, keeping the secret, in your own voice — while you still can?
