It's because the transition isn't jarring. Maybe the automobile felt similarly quiet back then. They did have trains and horse and buggies before the automobile I think.

YouTube was created February 2005, actually, but your point stands

I keep preaching this all the time. I highly recommend to watch Louis C.K. "Everythings Amazing & Nobodys Happy" (http://www.youtube.com/watch?v=8r1CZTLk-Gk)

These changes have killed boredom for the average Westerner. Life is becoming more awesome every second everywhere with these boons to entertainment, information, and growth. I figure that once libertarianism has beaten down Marxism and perspective on growth replaces whining about disparity, everyone will see what you're talking about.

Minor correction: Youtube was Feb 2005... it's 7 years old.

Doesn't at all detract from your point that things are changing. Re that, maybe I'm just in the Silicon Valley bubble, but many people around me do seem to have noticed. But I think you're right in general.

Maybe the speed of change has increased so rapidly that even historians will group many of these new technologies together and not give each much credit.

Maybe because the changes are all in the virtual world, they're "invisible" in the physical world. I think it was Charles Stross who said [paraphrased]: you could drop a time traveller from the 1960s into a modern city street, he wouldn't see many differences. The cars would look a bit melted and advertisements would have weird strings of characters instead of phone numbers, but that would be it.

Everyone would be carrying little black boxes in their pockets, and all the major changes of the last 10 years would just appear as icons on those boxes.

Just a minor correction.
I believe YouTube was out in 2005, which would make it 7 years old.

The development of converged networks is one of the hottest trends in technology today. Packets, packets, it's all about the packets…

Actually, the time-traveler would notice a few things:

* Women's lib
* The USSR and everything it represented and supported are gone.
* People are working longer and harder just to keep surviving in the physical world, while the virtual world is an Ian Banks-esque post-scarcity utopia.

Everything's dandy if you never pull your head out of the smartphone and ask why it's so damned hard to see a doctor or rent an apartment.
