If an agent’s long-term memory becomes a portable file, people could ask a personal AI to assemble a new tool for each task instead of choosing among fixed apps.
Software could shift from fixed products toward temporary tools shaped around each user. A personal agent would carry working habits, past decisions, and stated values from one task to the next, then assemble an interface from reliable components. This could make software more adaptable, but it would also place unusual power in the memory format and in whoever controls or interprets it.
At 9:20 in the evening, Jiwoo needs to reconcile expenses for a neighborhood club. She does not download an accounting app. Her agent builds a small ledger that follows her usual naming conventions, puts totals before categories, and disappears after exporting the finished records.
A portable memory file could expose years of sensitive context if it were copied, corrupted, or interpreted by an untrusted service. Generated tools could also behave unpredictably, and dependence might merely shift from app vendors to memory-format providers and agent platforms.
