It's important to remember that the internet is still very very new. Like the generation of digital natives are barely in adulthood. Sure, it's existed in some form for about 40 years, but most of the world didn't have access for the longest time. I wouldn't be surprised if we see massive changes in the next 20 years from the people who grew up on the web (specifically people outside the United States and Europe, where access was harder for a long time)
