Backing up data using DNA? Why this all sounds very far-fetched. Rail cannons, lasers, slipspace drives, smart glass, electric cars, mechs, robots, exoskeleton suits. The list goes on and on but alot of this is not the kind of stuff we can expect to see on an everyday basis. In fact it's more likely the stuff we'll see when we're old and wrinkly. It's future ideas for future generations to enjoy just like we can enjoy Iphones today.
