I weigh my options between going back to view alien lifeforms teaching the Egyptians how to build hydrogen-fueled powerplants (some call them pyramids) and distribute power wirelessly (Tesla later figured this out, but that is another story).
However, I think I'd prefer to warp into the future and witness Tomorrow's World. Listen to this new band which consists of a member from New Young Pony Club, and the other from Air. As evidenced, analog circuitry will exist in the future, as it resonates with an imperfect humanity.
