80s would be a fine place to have stopped, you even get the Gameboy!

But I also feel obligated to point out... the last time smallpox killed as many people in the US as social media does was well before 1980. The final US death was in the 40s.

There's a lot of meat between "We beat smallpox!" and "I can click a button and expose myself to commentary from any of 3 billion people." in terms of technology.
