(Just so I don't get accused of being off-topic:) My fiancee and I met via internet dating (Brad, use the site tied to onion.com...). We met very quickly, and I concur with the remarks about not communicating much before meeting. Our brains try to fill in the gaps, erroneously, as it turns out, and then we are disappointed by someone who is just not what we are looking for. And yes, Brad, before I decided to settle down, I met many women that way.
I chose to do it because I work at home, and I suspect my skills at chatting up women in bars are similar or inferior to Brad's ("So, read any Camus lately?")
Now, tink, speaking to what you're speaking to...I really think that we encounter more data in today's culture than we know how to process through experience - so we filter out a lot. As it happens, our brains are very fast at taking in data... but many of us don't get training in evaluating it critically, and especially not at changing over and over. So, the biggest risk of technological progress in my opinion is that our reach is exceeding our grasp by so much. We talk about how "young people 'get' technological change faster than older folks"... but they don't get any more skills at dealing, they are just exposed to the current situation while young and see it as "normal". They still reach a point (as we all do) where the change is far-reaching enough where it's not what you are used to, either, and that's when we have to get good at changing over and over. And where do you learn to change over and over?
Buddhists believe that unhappiness results from our grasping after constancy of self and of the universe in a universe that is inconstant. They might be right.
