A Superpower
for Everyone
The blind can see. The silenced can speak. Any child can be tutored. Anyone can be understood.
Abstract
For most of history, a missing sense meant a closed door. If you couldn't see the label, read the page, hear the language, or form the words, the world simply stayed shut. In roughly two years, the same AI that writes emails and code learned to describe a photograph, read a page aloud, translate a language in real time — and even turn a paralyzed man's brain signals back into his own voice. This brief is about a quieter revolution than productivity: a single technology, in nearly every pocket, handing people the one ability they were missing.
The number
people live with a significant disability — about 1 in 6 of us. For the first time, the AI already in their pocket is becoming their eyes, their voice, and their translator.
The reach
This isn't a demo. It's already in millions of hands.
Languages one free app now translates (Google Translate)
The four gifts
Four abilities, handed out for free.
Not one breakthrough — four, arriving at once, each aimed at a wall that used to divide people from the world and from each other.
Sight
Be My Eyes pairs a blind user's camera with GPT‑4's vision. Point the phone at anything — a thermostat, a menu, the mail, a child's drawing — and it describes what's there, out loud, in seconds.
A Voice
Voice cloning and brain-computer implants are giving speech back to people silenced by ALS and stroke — and not a robotic voice, but their own, rebuilt from old recordings.
A Teacher
Khanmigo is a patient, Socratic tutor that never just hands over the answer — it asks the next question. One-on-one, any subject, at 2 a.m., for the price of nothing.
A Common Tongue
Real-time AI translation now spans 200+ languages, turning a phone into an interpreter. One of the oldest walls between people — the language barrier — is quietly coming down.
One man, one voice
They gave him back his own voice.
In 2023, Casey Harrell — a 45-year-old father with ALS — had lost the ability to speak clearly. That July, surgeons at UC Davis implanted four small electrode arrays in the part of his brain that plans speech. Within minutes of switching the system on, it was turning his attempts to speak into words on a screen — and reading them aloud in a voice reconstructed from recordings of him made before ALS took it.
It reached 97.5% accuracy across a 125,000-word vocabulary — the fullest a brain-computer interface had ever restored conversational speech. His young daughter heard her father's real voice again. The work was published in the New England Journal of Medicine in August 2024.
“Not being able to communicate is so frustrating and demoralizing. It is like you are trapped. Something like this technology will help people back into life and society.” — Casey Harrell, on the UC Davis brain-computer interface (NEJM, 2024)
It did. Two years on, a June 2026 follow-up in Nature Medicine reported that Casey had used the implant at home, on his own, for more than 3,800 hours — speaking roughly two million words across 183,000 sentences, at about 56 words a minute, with word accuracy now near 99%. It gave him back not just a sentence, but a life: he uses it daily and has returned to full-time work as an environmental advocate. He describes a life once again “full of dynamic action … with friends and family, with colleagues” — one that “allows me to communicate more in my natural way … than any other technology” he has experienced.
The takeaway
A superpower isn't flight or super-strength.
It's the ability you were missing.
To see a face. To say your own name. To understand a stranger. To be taught well. For most of history, if you were born without one of these — or lost it — the world stayed closed. AI is not perfect, and it is not finished. But quietly, and for millions of people at once, it is opening doors that were shut for a lifetime. That may be the most important thing it ever does.
