I personally became interested in 3D printing because I attended the 3D printing conference back in November 2015. Some of the experts in the field actually came to campus to present us the most exciting news and discussions about 3D printing, including John Hornick. I very much liked his presentation on last Monday, and some of his points were very inspiring.

Mr. Hornick mentioned the mature of 3D printing technology would allow people to make things away from control, and until now the legislation regarding the subject matter is still in absence. This reminds me of scenes in science fiction movies, in which individuals with high intelligence rule the world with their own rules. I know this might sound ridiculous and might not happen in the near future, but do notice technology advances exponentially. I mean look at these Ferraris of the future http://3dprintingindustry.com/2016/01/27/these-are-the-ferraris-of-the-future-3d-printed-by-skorpion/?utm_source=Facebook&utm_medium=social&utm_campaign=3DPI+Facebook, you can basically make them by yourself in theory. I personally think with the maturity of 3D printing, the margin of individual ability would be extended enormously, and the power structure of the society might be very different from what it is like today. However, the dangerous side of this technology is not to afraid of, but to be planned ahead and controlled effectively.
