Everybody thought that by the year 2000 we would be in flying cars and everything would be so futuristic....we are getting very close to that scenario tho...when i first saw that scene in "Aliens" where Ripley and that other guy was "face-timing" on the monitor, i thought to myse'f " haha that will never happen, and i won't live to see tech like that"
Fast forward and now iphones have facetime tech that allows you to see other people with crystal-clear clarity....facial structure security, pupil layered security, etc...the stuff we saw in sci-fi joints ages ago are a true reality today....
