Crazy thing is you don't have to be that old to remember the time without internet. I'm in my mid 30s and while internet did exist of course, I traveled to many places in the world with my parents without it because it was not widespread and useful at all just 25 years ago. Solely relying on the Lonely Planet and what people you meet tell you, using the phone-boots to call. Actually going to a city without a hotel reservation and just walk into places with a hotel sign to see if they have a room. So different than how I'm travelling now.

Internet still is something very new to humanity, and we are still in its early stages I think, even though it feels stale sometimes (with Google always there for example). A good way to see this is if you dive into the technology that the internet is build on. It's still the (pretty crappy) system that it was when invented. Just with a lot of stuff build on top of it. I think at some point in the far future we will build a completely new sort of internet based on much better protocols.

yes, it seems like we're already in the beginning of a long drawn out singularity. maybe it's basically as fast as we can advance right now. there may be other bottlenecks.
