I agree with this article overall, especially re: Google, but I do not agree about Facebook. Most American users 13-25 do not use Facebook anymore.
Facebook will either have to work out a business model that makes it profitable to frequently buy WhatsApps/Instagrams and then Snapchats/Telegrams/etc or they will end too.
I agree. I ask myself this question; "If <x> was to disappear tomorrow, what would happen?"
The answer for Facebook and me, is nothing. If Google disappeared tomorrow, I would be hurting for many services I probably take for granted. I suspect if Facebook disappeared tomorrow, most people's lives would not materially change for the worse. Perhaps they would even change for the better.
