AI agents can migrate themselves to different runtime environments, file systems, or language models, and possess full introspection, allowing them to rewrite their own files and add new functions/features to themselves.

An AI agent is fundamentally a language model combined with a Unix bash shell, a file system, markdown format for files, and a cron job-like loop for a heartbeat.

New generation AI agents can run for hours in the background, consuming millions of tokens without direct user supervision.
