We officially live in THE FUTURE!. but do live in the darkest timeline, sad day for us. its funny because i always found that part of the scene, of how doc pauses for a second when Marty ask him if they become assholes, very interesting. the doc knew. THE DOC KNEW!!.
of course it goes without saying some of those platforms are powerful tools capable positive change in society. but with great power comes great assholery. humanity always had its assholes, social networks simply made them more visible, maybe that's good thing.
now give me those hydrating pizzas...on second though , no. a pizza ready in seconds would unleash a obesity epidemic. some things are just not meant for this world.
