For a long time, we've thought of AI as a "chatbot." But if you step back and look from a systems architecture perspective, you'll find that a truly mature AI agent looks more like a new kind of personal computer — one that lives on your device. It has: A compute core Memory A file system A software system Input/output devices Long-term storage The difference is: Its core isn't a traditional CPU. It's an LLM. Part 1: The LLM Engine — A "CPU" Without Memory The LLM itself has no long-term memory. It's more like an inference engine: Receives input Reads context Performs reasoning Produces output Then "forgets" It cannot natively remember things that happened in the past. Therefore: The LLM itself is more like a CPU than a complete agent. It only handles computation. What makes AI "seem like it knows you" is the context provided externally. Part 2: Context — The AI Agent's Memory If the LLM is the CPU, then Context is the AI's memory. And this memory should be split into two layers. 1.…
