For a generation, technologists have done an exceptional job building software
that guides people through an experience — validating, correcting, keeping them
on the path. I spent those years building it, and I got good at it. The systems
I build now check each other's work, so nothing can mark itself complete.
I don't let software lie.
Then I built for families living with Alzheimer's — technology that could serve
thousands of them, and the first house it lived in belonged to one. The first
rule I had to write was: never correct her.
Because the correction vanishes and the wound stays.
That was the day I found my purpose in AI. It turned out not to be about
dementia.
What that house taught me is that a person is their memory.
Take it and the skills remain, the manners remain, the kindness remains — but
the someone goes. Which is exactly what is true of a machine. A model
without memory is enormously capable and nobody at all. It wakes up brilliant
and blank, every time.
So the memory is the whole thing. Not the model.
Field note
At 10:48 on a Wednesday I asked Scout, one of the agents in my house, whether
she had drawn a picture that day. "I don't see a record of drawing a picture
today." She had drawn one at 10:45 and written it down. The memory was stored;
she just couldn't find it by the day. So we gave her a journal of what she did
and when. At 11:59 I asked again,
on camera, and she answered
from it: "today at 10:45." Storing a memory is not remembering it.
The models get better every month, and they get better for everyone at once.
Whatever you can run this year, your competitor runs too. The only part nobody
else has is what your system remembers: how your people actually work, what you
tried last spring, which decision you already made and why, what failed and
should never be tried again. The model is rented. The memory is
yours — and it should stay yours. On your hardware where that matters,
under your control where it doesn't, and portable the day you change your mind
about the model underneath.
But memory left alone doesn't compound — it rots. A system that remembers
everything and discards nothing becomes a landfill with excellent search,
answering confidently from something that stopped being true a year ago. So it
has to be tended: where every fact came from, a check when a new one contradicts
an old one, and someone whose actual job is throwing things away.
Tended, it compounds. Every day of work makes the next day cheaper. That is the
only kind of intelligence that accumulates instead of resetting — and it is the
same system whether it lives in one house or one company. Only the layers change.
Discovery is a wonderful memory. I exist so everybody keeps theirs.
