Good tools, over time, retreat out of sight. Like an electrical outlet, like a faucet, they seep into the ambient around us. AI is walking that same path. A 15-year-old MIT project finally became a consumer product.
Have you ever counted how many times you open your phone in a day? The average is 150 times a day. Divide that by 16 waking hours, and it's once every 6 minutes. In a meeting, at a meal, even on the toilet, we reach for the phone. We are trapped in front of this little rectangle. One question — is a good tool supposed to hold you in front of itself, or release you?
This essay is about that question. Anyone who uses a smartphone can follow along — we'll go slowly. Today's example is a wearable called Humane AI Pin, but the principle applies to any future device. Three years from now, even if the company Humane is gone, the spine of this essay still holds.
Let's start with the principle. Good tools share one thing — over time, they retreat out of sight. Think of electricity. A hundred years ago, bringing electricity into a house was a big event. A huge generator sat in the middle of the living room. Now, you don't even know where the outlets are. They're hidden in the walls. Electricity didn't go away. It got much more plentiful. Just invisible.
Water is the same. Long ago the well was the center of the village. Now the faucet sits in a kitchen corner. Air conditioners used to occupy the living room. Now they're hidden in the ceiling. Good technology doesn't get smaller as it grows — it grows into the surrounding space. In English that's "ambient." It means "wrapped around, in the surroundings."
But oddly, with computers this common sense ran backwards. Computers came into the living room. Onto the desk, then onto the lap, then onto the palm. They crawled toward our eyes. The smartphone is the peak of this. Why were computers the exception? Simple — the technology wasn't detached yet. Now it's time for it to detach.
Let's look at one recent device. Humane AI Pin. A coin-sized wearable that magnets to your clothes. A small projector on the front, a battery on the back. The two halves clamp across the fabric. No display. Instead, it projects information onto your palm. You control it with finger gestures. Shipped to consumers in 2024.
But the prototype for this device existed 15 years ago. The 2009 "Sixth Sense" project at MIT Media Lab. Same method. Chest projector, color markers on fingers, display on the palm. Back then, computer vision was too weak, so they had to wear red, blue, and green tape on fingertips. Today, AI recognizes bare hands without any markers. It took 15 years in between.
Beyond Humane AI Pin, Ray-Ban Meta smart glasses, Apple Vision Pro, and many pendant-style AI devices from Chinese startups are all moving the same way. From screen to space. No matter which company ships what name next, this direction repeats. The principle demands it.
To make it easier, picture an air purifier. Ten years ago, an air purifier sat in the middle of the living room. The size of a fridge, a loud fan. What about now? It hangs thin on a wall, or integrates with the AC, or hides in the ceiling. The air purifier didn't disappear. It seeped into the ambient.
AI is going the same way.
The air purifier only alerts you when air is bad. The rest of the time, you forget it exists. AI should go that way. Appear only when needed, and be forgotten the rest of the time.
Concrete numbers give a sense of this shift. The average adult spends 4 hours 30 minutes per day on their phone. Turns the screen on 150 times. Subtract sleep, and 28% of waking hours is spent in front of the screen. A quarter of our life inside a little rectangle.
Now the other side. A well-designed ambient computing device grabs attention only 5~15 times a day. Smartwatch notifications are roughly at that level. From 150 down to 10 — one-fifteenth. And those 10 are only truly necessary. The rest of the time the device sits quietly in the background.
Here's the first aha.
Smarter AI doesn't mean speaking more. It means speaking only when needed, and staying silent the rest of the time.
The ChatGPT we use now answers ten times when asked ten times. Too talkative. Truly smart AI knows the right moments without being asked, and shuts its own mouth when not needed. That's the core of ambient computing.
So what should you actually do. Just one question to wear on your body.
"How often am I staring at this tool?"
This question automates your tool choices for the next ten years. Split the answer three ways.
Most of today's smartphones, desktops, and chat AI fall here. These tools will drop to a supporting role. Start practicing reducing dependence slowly.
Smartwatches, AirPods, and similar wearables. Less attention stolen. Move your investment and habits this direction.
Speakers woven into the space, an AI Pin controlled by gesture, glasses controlled by gaze. In 2~5 years these come down to consumer pricing. Learn them early and you'll be ahead through the transition.
MR_5PM, who made this video, offered one analogy. How do you know it's raining? Some of you open a weather app. But most of us know from the sound of rain. The sound through the window, the humid smell, the cool on the skin. All of this is "ambient information." Information you learn without focusing on it.
AI Pin is heading that direction. It listens to your surroundings 24 hours and only intervenes at important moments — appointment nearing, a child crying, an alarm. Privacy is a real issue. Humane designed it so the other person's voice is only recorded with consent. Not perfect, but a step.
Let's wrap up.
Good tools eventually disappear. Electricity, water, air purifiers all did. AI walks the same path. I explained this through Humane AI Pin and MIT Sixth Sense, but the same applies to every future device, every upcoming AI product. Specific names change. The direction — seeping into the surroundings — repeats.
Just one question to wear — "How often am I staring at this tool?" This single question automates your tool choices. Invest in tools that make you look at screens less and at the world more. Reducing screen time is not a willpower problem but a tool-choice problem.
What lasts is not someone good at smartphones, but someone who knows when AI should disappear. This sense comes not from a spec sheet but from the history of good tools — electricity, water, air purifiers. Three years from now, even when Humane AI Pin is gone, the principle you learned today still works. Devices change. Disappearance doesn't.
Screen. Ambient. Gone.
