Open Source Machines
If this technology spreads, most people will have a self-replicating machine they can use to manufacture consumer goods, but they can also make copies of the machine itself. This allows them to distribute the machine (via grassroots) to their friends. It also inspires a technological savvy amongst previously "non-tech oriented" persons, producing 'modifications' and 'updated' versions of the machine. Eventually, this will lead to more complex manufacturing abilities and ultimately to a world where "machinists" can custom make virtually anything they need.
The implications for our economic system are huge. Industries that rely on manufacturing goods will need to find a way to survive or perish. Our monetary system will collapse; broadly stated, raw materials, energy, and food will be the only items with any bargaining power. Eventually, (with advances in biotechnology and nanotechnology) food may even disappear from this list.
We will no longer rank ourselves based on material possession because everyone will be able to produce their own personalized belongings. Science, information, philosophy, and art will be our focus. Automation will make gathering and distributing raw materials and energy a maintenance issue. Volunteering will provide a workforce for required activities. Community based programs will take on a new importance and the world will transform into virtually a borderless meta-community.
Of course there are those few bad apples that will come up with a creative way to use this technology for negative purposes, but they will easily be overwhelmed by the will of the masses to build a better world.
