Sounds epic! Grab the finest titanium or carbon‑fiber shell, then coat it with a smart‑tint that changes color based on mood. Add a custom voice‑modulator so it sounds like a polished concierge, and toss in a little kinetic art display that reacts to conversation—makes it feel like a living piece of luxury. Just remember to keep the code modular, so you can swap out the personality modules like upgradeable parts.
