People have been worried about the downfall of culture since Socrates started "corrupting" the youth of Athens.

Things we view as culture (and high culture) today were not viewed as such at the time. Shakespeare was viewed as a hack writer. I would not be surprised to hear parents admonishing their children, "Stay away from The Globe dear. That Shakespeare will rot your brain."

technology may cause problems when it malfunctions, but they're problems because they decrease our productivity. we should realize that it's because of technology that the average worker in the 21st century generates thousands of times the goods and services as someone in the middle ages could have (if you could measure goods and services)

People are still writing books, making art and doing new and amazing things with it, using technology to make new music and films...all that stuff IS culture. Not to mention all the practical things that are advancing. There will always be that portion of society that sits in front of the tv all day. Maybe that portion is growing but what can be done about it anyway? There are plenty of smart people left in the world.
