Completely wrong, obviously. Coming from a position of tech savvy early adopter, I totally underestimated:
- the impact that mobile had on the landscape. For most of those over 30, the internet was for work, not for "group socializing". I think mobile normalized the practice of spending hours a day on social media for average users.
- how "sticky" older users are. Once they're on Facebook, they stay on Facebook.
- Zuck's adaptability, and the difference between "Facebook the platform" and "Facebook the company". I mean, I was partially right about the exodus to the Next Big Thing (TM). That's exactly why Zuck just went out and just bought it (Instagram and WhatsApp in particular).
That being said, I still think there's a coming reckoning on digital advertising. I hear so many complaints about poor ROI, click inflation/fraud and general dissatisfaction (e.g. Basecamp competitors bidding on the search term "Basecamp"). I can't help but think there'll be a shift in spend towards advertising on more "conventional" media (Spotify, Netflix, YouTube).
