One device that will shape the World

I think that every material is made of atoms, where atoms are made of electrons, protons and neutrons that are electrical charges.

Every known element are made of atoms and combining the disposition and the number of these three electrical charges, we have different elements.

So everything is made of electrical charges.

If we think that we can replicate these elements combining the electrical charges yourself, we can create a 3d printer that can print out EVERYTHING we want.

Then we can have a global database where everything is mapped and shared between the word population.

Everyone can have everything they want and then there is the 3d printer for everything, for free.

So in the database we can have the original Neapolitan pizza, so we can ask the 3d printer to create all the elements needed to replicate the perfect Neapolitan pizza.

We can have everything from food to goods to human organs to everything we want.

The only thing that the 3d printer will require is electrical energy that will be converted in atoms, molecules and so on.

So People can spend their time building their home with the 3d printer as they like, educating their children, studying if they want, relaxing, creating a new type of food or drink or a new machine.
