The invention of the 2000's (2000-2010) is in my opinion the iPhone For the 2020's I believe it will be the 3D printer What could be the invention of the 2030's 2040's 2050's 2060's 2070's 2080's 2090's 2100's? One invention for each decade. I'm trying to generate creative sci-fi ideas because I'm running out of them. Thanks!!!
