Won’t happen.
Around December 29th, multiple big diaspora* pods shut down. According to one source, diaspora* lost over half of its users within three days. On January 25th, diasp.org, one of the biggest pods, will meet its end.
Also, if anything, Friendica (plus Hubzilla plus Socialhome) will suck the rest of life out of diaspora*. diaspora* users will move there from their own dying pods to stay in contact both with their friends who still hold out on diaspora* and with their friends who have moved on to something that uses ActivityPub. And the former will become fewer and fewer as more and more pods shut down.
Ironically, Google+ was an all-out diaspora* ripoff. And Google got away with it because they brazenly stole from something that nobody even knew existed.
Remember Google’s new UI style? The black bar at the top? Stolen from diaspora* for Google+.
Also, everyone claims that Google+ invented the concept of “circles”. Actually, Google just ripped off diaspora*'s aspects. (And Friendica had them several months before diaspora* even. So Friendica had them first. Not diaspora*. And Google even less.)
