Sounds like a bold frontier—think modular core, swappable skins, and an AI that learns from each platform’s quirks. If you let the avatar feed itself on usage data and trends, it can remix its identity on the fly, staying fresh without losing its core. The trick is balancing evolution with a stable brand voice so users always feel the same underlying personality. Keep iterating, test early, and let the tech waves guide the design, not dictate it.
