People forget that "the future is here, it's just unevenly distributed".
I also discovered Google in 1999, and then worked there a decade later. I remember listening to the earnings calls around 2011-2012, and my coworkers would express disbelief in the questions that financial analysts would ask, because they totally missed the key drivers of our business performance. "It's simple," someone older and wiser told me, "they assume that the Internet is tapped out, no more people are going to go online, and so the only possible driver of higher revenue is higher cost per click." In reality, search queries increased 4x between 2009-2012. Large numbers of people were still discovering the Internet for the first time in the early 2010s. Hell, large numbers of people are still discovering the Internet for the first time now - Google still has a "next billion users" initiative (largely focused on India and South/Southeast Asia), and only about 35% of the world population are Internet users.
This is not true in the early 2000s - I remember people at school (UK) using Google in the late 90s.
