"AI agent" really rolls off the tongue, doesn't it? Compare that to what's actually under the hood: some straightforward code connecting language models to a toolkit of functions. Ask the LLM to parse user input, trigger the right tools, execute tasks—nothing revolutionary there. Yet slap the "agent" label on it and suddenly everyone's excited. It's the same old wrapper dressed up in fresh terminology. Classic marketing move: take something fairly vanilla and make it sound like the future.
