TV use was higher in the 2000s than it was in the 1980s/1990s. TV viewing hours steadily rose from 1949 until finally peaking in 2010.[1]
But when TV finally peaked in 2010, did overall screen time go down? No. It kept going up.[2] Obviously, this is when the masses went all-in on smartphones, social media, and the internet.
Screen usage basically never went down. It has only gone up.
So I only see anyone getting tired of smartphones and actually using them less if they've found something more addictive to replace them.

These things rarely happen organically anymore unless "forced" in one way or the other...
It's the same now with fb and these other old format social media sites. People just stop doing it. With that said I literally think fb will be with us for another 50 years as the people who are still on there are great marks and they won't be leaving until they 'age out'.
