You once defined the future of personal computers.
You didn’t follow markets. You created them.
You once made tools that amplified creativity instead of extracting attention.
You taught an entire generation what innovation looked like.

We believed that company still existed. Today, the most valuable technology company in the world ships incremental upgrades while the next computing frontier sits wide open.

Eight years to add a heart-rate sensor to AirPods.
Six months for Walnut to design, engineer, and a consumer-use neural wearable headband.

That isn’t a matter of resources. It’s a matter of resolve.

This isn’t an attack. It’s a welcome.
Because the gap between what can be built and what does ship has grown too large to ignore. And history shows that when incumbents slow down, someone else defines the era.

At Walnut, we’re building the next category of wearables. Technology that lives on the body, responds to intention, and treats human data as human.

So welcome, Apple. Seriously.
To the most important technological transition since personal computing.

We’ll see who’s ready.
