Digital twinning [Information Technology Virtual Reality]

DO YOU HAVE an avatar? What does it look like? Some middle-earth orc-like being or blue-skinned svelte alien form? Does it look like you? It may be a Japanese anime version of you, or a Lego people version. Either way, it's unlikely it looks exactly like you. Yet in the future we may all have and even need avatars that do look exactly like us, a kind of digital twin existing in cyberspace. They may even talk like us and walk like us.
