Are you ready to experience life as it may be in the future?Here are some interesting points to learn
about the future.
     Artificial intelligence:Many years down the road humans  might not even be recognizable because
artificial intelligence  (also known as AI) will have combined with our natural  states.Scientists are learning more about the human brain every day, and they are working toward making smart robots we can use to
help us.Some people say that nanobots-supertiny robots-may help us in invisible (看不见的) ways in the
future.They say they will be everywhere, outnumbering humans many times over!
      Nanotechnology:This is the ability to make tools and  helpful robots that are a billion times smaller
than we can see.Scientists have already made many nanosized tools that they can use.When this science
is improved and becomes more common and affordable, it will change everything.
      Braintocomputer communication:Nanocomputers will probably be linked to your thoughts, voice and
emotions, and be able to react to your needs.In the future people will rely on wireless technology and
everyone and everything  will be linked.Your brain will be able to receive information  from computers
to fill your head with knowledge or teach you new things.When you want to learn a new skateboarding
trick or dance move, nanocomputers will send the information to your brain and allow your body to use
the tips and apply them-no studying involved!
      Virtual reality:You already love virtualreality games-they make imaginary worlds in which you can
play. But what if it allows you to have a cool new school?Virtual worlds are being created so
computergenerated environments will allow you to learn school lessons with your teacher and your
friends seemingly present without actually being there.Technology will give you a 3D image and link it to
your brain in a way that makes you actually feel as if you were there.
