Artificial_intelligence research & Ray-Kurzweil have become so intertwined over the years.

Someone else had a 21 year head start over Ray_Kurzweil.

Indeed, many regard Marvin_Minsky, winner of the 1969 Turing_Award to be a bridge of research & knowledge between the 20th & 21st centuries. http://web.media.mit.edu/~minsky ,

A Printable Matter

3D_printing is a fascinating & potentially dangerous form of Printable Matter.

So, in addition to the occasional fire concern another issue looms for any train, bridge, tunnel or building.
Obviously, 3D printed objects will be under strict control in certain environments.

Collectors & movie set props would undoubtedly like to have the quick ability to make a nonfunctional replica of various items. The M1911_pistol started its service_history in the year 1,911.

1,911 , 911 , 191 , 119 , 1119 , etc.

Some flights have already had enough disastrous problems.

Remember, owning & operating a Porsche_911 doesn't necessarily make you a more ferocious & careless driver. Some movie & TV productions might not want to have a totally CGI set or resort to actually destroying real cars & things. Therefore, 3D printed replicas can provide for a more realistic looking movie set. The 2013 movie, Oz_the_Great_and_Powerful used a combination of real actors & sets integrated with CGI effects.

Lots of collectors might want to have 3D replicas of big game animals or guns. For years, many people have had replicas of various paintings & other art forms.
