 * Think for yourself,
 * Question authority.
 *
 * Throughout human history, as our species has faced the frightening,
 * terrorizing fact that we do not know who we are or where we are
 * going in this ocean of chaos. It has been the authorities, the
 * political, the religious, the education authorities who attempted to
 * comfort us by giving us order, rules, regulations, informing, forming
 * in our minds their view of reality.
 * To think for yourself you must question authority and learn how to
 * put yourself in a state of vulnerable open-mindedness, chaotic,
 * confused vulnerability to inform yourself.
 * 
 * Think for yourself,
 * Question authority.
 *
 * Think for yourself...

 * recently, at a local bar, it was brought to my attention that not all people
 * believe in evolution.  so to prove that evolution is real and people and all
 * animals evolve i present the example of wisdom teeth.  if it were not for
 * the advances in dentistry, a larger number of people that develop wisdom teeth
 * would die from impacted wisdom teeth (ie. they become infected, etc).
 * thus people who did not form wisdom teeth would become a higher and 
 * higher percentage of the population.
 * 
 * evolution.

 * it seems ironic that man creates a machine as an extension of himself/herself
 * in order to progress the achievements of mankind.  computers have taken an
 * odd twist over the years and the target market of most software is the
 * bottom ten percent of the intellectual barrel.  vendors that come to mind
 * are microsoft and apple.  computers, now being easy to use, can be used to
 * ensure people don't have to think either.  enter the call center.  hundreds
 * of people sitting at tiny desks with a crt aimed at their face like a shotgun
 * ready to take their last remaining brain cells, reading scripted conversations
 * and responses to people over the phone. answers received are carefully worded
 * by lawyers, technical staff, and management to ensure that the armies of
 * text regurgitation drones don't spew anything that would make the company
 * liable and is politically sound while providing a vague answer for the
 * statistically common problems faced by users seeking support.  computers
 * for the general populous aren't an extension of man.  mankind is an extension
 * of computers.  pray that your vulcan-like masters don't crash or you might
 * actually have to think.

 * I think yeah, development has pushed us away from other people.
 * You know, a lot of times people are rude because they want like immediate
 * access or immediate information.
 * You know some things in life can't be immediate, sometimes you gotta wait
 * and let things happen. People are like increasingly rude. Like I'll say
 * someone will get in a cab, we'll say ";I'll get em there in 5 minutes.";
 * And they'll say, ";It should only take 3.";
 * Now who gives a shit if it takes 5 minutes or 3 minutes, who cares?
 * At the end of your life nobody's gonna put shit I got in a cab in
 * five-seven minutes instead of three.
 * It doesn't matter!
 * Technology has made us slaves of the time.
 * A lot of people that are really have technical jobs they're slaves to time.
 * Time's the essences of life it seems like. And they're basically like losing
 * it, they're losing the essence of their life because, you know, their life
 * is like just going away and, they're not enjoying it because their so
 * engrossed in efficiency and productivity and shit like that.
 * It's almost sad.

 * I think there's going to be a backlash against technology.
 * You know, I don't know what's gonna cause it, I hope it won't be any
 * environmental disaster shit, you know, for sure for my kids that wanna live
 * a better life. Not so much materially but I want a peaceful life.
 * You know sometimes it's good just to go in the woods and just go hiking and
 * get back in touch with yourself and nature. You know, then you come back here
 * and you realize that this is like, ludicrous, all this emphasis on technology
 *  and 50 different internet devices and shit and internet devices you can put 
 * in your pocket. Sometimes I feel threatened by it but you know, that's the
 * future and I am a man of the past.
 * You know, I'm a low-tech man in a high-tech world. I mean it's fact man.
 * I'm a low-tech man in a high-tech world there ain't shit I can do about it
 * because, you know, the world's changing and I'm not and you know, maybe
 * I don't wanna change.
 * Maybe the people I associate with are like me.
 * You know, what's going on we can't use our brains?!
 * It's being a person..
 * You know it's being a fucking person man...
