Once the nerds figure out fusion, I'm building replicators. With unlimited time, I could develop the quantum theory and build the machinery to manipulate quantum states to exchange stupid amounts of energy for matter. It's just a matter of recording an object's complete quantum state and rewriting it onto the fabric of reality. Simple, really.
