When a family lives across time zones

A separated family needs memory differently: it substitutes for daily presence. These analyses are about what exactly is preserved and who receives it afterwards.

Inheritance and memory

Who inherits your accounts if you do nothing

Four distinctions carry the whole subject of digital inheritance: an account is a permission and not a thing; the tools hand over a copy and not access; a purchase in a store is a licence and not a file; an assistant's memory holds facts about a person rather than their words. The rules of Google, Apple, Meta, Microsoft, Amazon and Steam are quoted from their own agreements, and the ending lists what can genuinely be switched on in one evening.

Memory and ethics

What exactly vanishes between sessions

Separating the verifiable from the interpreted: a model really is stateless between calls, and that is not a metaphor. Choice and awareness cannot be checked — and the engineering does not depend on that answer.

Memory and vector search

Permanence without search is a warehouse

Immutable storage answers for a record surviving and promises nothing about whether you will ever find it again. This analysis follows the second guarantee: an HNSW graph cut along meaning on top of a DHT, a Groth16 proof of distance with dimensionality squeezed from 1536 to 128, the pricing formula for a query, and the half of every fee set aside in advance for permanent storage.

Inheritance and memory

The timer that decides you are gone

An analysis of the Inheritance Protocol: why the silence threshold is 360 days, what the seven-day warning does, why the key is split by Shamir's scheme, and three failures possible even when the mechanism works perfectly.
