You mean like Twitter? 12 years later, it's not imploding.
Or maybe you mean like Facebook. 14 years later, it's still growing, not imploding.
Social is a mature segment now, the big winners are not going to implode as MySpace and Friendster did. Those companies lost because they were replaced by superior products, they didn't just magically implode, they were beaten in the market.
Show me the competitive threat to Facebook, Instagram, Whatsapp, Twitter, etc. There aren't any, the race is over.
