Personally I think that drone technology needs to be perfected. Now, before you go full retard, this is why: Drone technology automates transportation. Driverless cars, and pilotless planes all are made possible by drone tech. This leads me to step 2. The next thing we need is perfected recycling technology. It needs to be simple, and completely automated. Finally, home based 3D printing for small goods, and automated factories for big items. Factories that can build anything. Add this up and anyone in the world can have any item they want for next to nothing. Automate food production and these steps effectively kill both communism and capitalism as working concepts. At least until the drones become aware and kill us...
