I'm with you that a site of that critical size probably won't die, not within a decade.
The same was AOL is actually not completely dead. Yahoo! is not dead, Digg isn't either, neither did MySpace. And I'd totally see Tumblr having a full come back to the front of the stage.
Another way to put it could be "dead to us" for any specific value of "us".
AOL and Yahoo had advertising revenues Reddit could only dream of.
As it stands, a huge chunk of Reddit's content is Twitter and Tiktok reposts. Older users like me enjoyed that because I didn't want to sign up for Twitter and TT. The younger app centric users that Reddit is pivoting to probably have Twitter and TT accounts. So what value is Reddit providing?
