The world changes but does the human condition fundamentally change?
I think it does, but not as quickly as the world changes. The available information load is
way ahead of most people's ability to cope with it, but at least in the developed world, you can't realistically opt out. I get funny looks just for telling people no, I don't do Twitter or Facebook -- even after the latest revelation of how they've fucked up user security
again. I actually get less grief telling people I don't have cable TV.
Even the option to not engage is taken forcibly away from us: my bus ride to work was an opportunity to get my brain engaged in the morning, or to start winding it down in the afternoon -- but I now the city bus line blasts audio ads loud enough to overwhelm my earbuds even when I have the volume turned up too far, literally every one to two minutes.
So here we sit, possessors of remarkable biological computers inside our skulls finely tuned to make connections and find patterns, and we spend almost all our waking hours in a state of sensory overload. It becomes like trying to find patterns in static -- and the way we are wired, we
can, but we can't tell that accidental patterns are meaningless.
