Why the brain should run on your machine.

Somewhere we agreed the smart part of software lives in a warehouse, and our lives commute there to be understood.

For most software that's fine. Personal software is different: ask what the thing is actually for, and the architecture follows. Its subject is you. Your pages, your messages, your half-thoughts. Shipping those to a stranger's computer to be read is a strange way to keep a secret.

Run the model on your machine and nothing leaves the room. No transit, no logs, no training set. Privacy stops being a policy and becomes wiring. You also get speed: the loop closes in about the time it takes to think.

That's the bet behind Meteor, a browser with the model inside it: summarize, ask, and get help right where you're reading, with no round-trip. It's the same reason Carillon's brain runs on your Mac and keeps the cloud thin.

The biggest models still live in warehouses, and the hardest jobs are worth the trip. So the cloud stays a tool we reach for on purpose. The rule is short: the ordinary stays home, and what leaves, leaves because you sent it.
