How long until we get a truly personal AI like Jarvis ?

A viral Reddit discussion is capturing the imagination of the AI community by asking a fundamental question: How long until we get a truly personal AI like Jarvis? The vision isn't for a smarter chatbot, but for a persistent, local AI assistant with perfect memory. This system would function as a private 'second brain,' using technologies like RAG (retrieval-augmented generation) to reliably recall every detail of your life—from a friend's movie recommendation weeks ago to a fleeting idea captured in a conversation.

The core innovation is structured, reliable long-term memory. Unlike current AI models that are stateless or have limited context windows, this Jarvis-like agent would build a searchable knowledge base from your daily interactions. It would run entirely locally, ensuring privacy, and could eventually integrate with wearables like smart glasses to capture context automatically. While pieces of this vision exist in note-taking apps and local LLMs, a complete, seamless system remains a significant unsolved technical challenge, representing a major frontier in human-computer interaction.
