As a reaction to the OpenAI + io announcement two weeks ago, Christopher Butler imagines a mesh computing device network he calls “personal ambient computing”:
…I keep thinking back to Star Trek, and how the device that probably inspired the least wonder in me as a child is the one that seems most relevant now: the Federation’s wearables. Every officer wore a communicator pin — a kind of Humane Pin light — but they also all wore smaller pins at their collars signifying rank. In hindsight, it seems like those collar pins, which were discs the size of a watch battery, could have formed some kind of wearable, personal mesh network. And that idea got me going…
He describes the device as a standardized disc that can be attached to any enclosure. I love his illustration too:

Christopher Butler: “I imagine a magnetic edge system that allows the disc to snap into various enclosures — wristwatches, handhelds, desktop displays, wearable bands, necklaces, clips, and chargers.”
Essentially, it’s an always-on, always observing personal AI.
