Grammarly built a $700 million business on one capability, then generative AI made that capability too easy to remain a destination. Its rename to Superhuman is the cleanest case study yet of the shift from apps to stacks. … readGrammarly Was the App | App to Stack
Habituation closes every gap that exposure can reach — except two. Below your model, noise has no structure to learn; above it, awe has too much to hold. Both pay out surprise forever, and only one of them changes you — which is why the feed sells the other. … readNoise and Awe
To every system trained on your behavior, you are the Actual: your surprise is its error, and the cheapest way to lower that error is not to know you better but to make you easier to predict. The self it serves back is the one that stops generating news. … readThe Predicted Self
A joke is the smallest machine ever built for manufacturing surprise — and the punchline is, by construction, the token an expectation engine wants least. That is why the models that finish our sentences reach the shape of a joke and miss the inside, and why the day they stop missing is worth watching. … readThe Least Likely Token

A personal stack has no halting condition tied to its owner’s pulse. Death used to reach every channel at once, as silence; an absorbed life can keep filing, renewing, and replying on schedule — which is why the stopping rule belongs in your estate, and why some channels should be allowed to die with you. … readSurvived by the Stack

The argument is not that artificial intelligence never needs data. The argument is that a human should not have to prepare the intelligence before the intelligence can begin working. … readPress Enter and Walk Away
The synthetic subconscious does not delete prediction error; it defers it. Every routine the stack absorbs stops updating your model of the world, and the gap compounds quietly until an outage, a drift, or an exit calls the whole balance due at once. … readSurprise Debt
