A few other concepts-become-reality:
Minority Report's face scanner is now common tech on smartphones and
tablet computers. Biometric scans are commonplace today--fingerprint
scanners and face recognition technology can be found from the Apple
i-phone to Sony's PS4. Most of us are familiar with the “replicators”
in the Star Trek series—devices that could generate items out of
thin air. Yet today, this isn't as far from reality as we might
think, considering the 3D-printing revolution. Just buy the plans for
an object online, and your personal 3D-printer can produce the item
for you in minutes. Would you like to send a copy of your child's
clay sculpture to her grandparents that live on the other side of the
country? Just place the object on a scanner, scan, and send the data
to their 3D printer. They'll have a physical copy in just minutes.
Even houses are being built by 3D printers, and complex objects, like
firearms, can also be printed as parts to be assembled. Just imagine
what the pirating problem will be like in the future when everyone
has one of these!
