  Digital life, a form of life generated by computer programs or artificial
intelligence systems, it possesses self-awareness, thinking abilities,
emotions, and subjective consciousness. Achieving it involves complex neural
networks, multi-modal sensory integration [1, 2], feedback mechanisms, and
self-referential processing [3]. Injecting prior knowledge into digital life
structures is a critical step. It guides digital entities' understanding of the
world, decision-making, and interactions. We can customize and personalize
digital life, it includes adjusting intelligence levels, character settings,
personality traits, and behavioral characteristics. Virtual environments
facilitate efficient and controlled development, allowing user interaction,
observation, and active participation in digital life's growth. Researchers
benefit from controlled experiments, driving technological advancements. The
fusion of digital life into the real world offers exciting possibilities for
human-digital entity collaboration and coexistence.
