My bet would be that the next big social platform will come about when Apple and Google agree an open messaging platform for Android and iOS.

That will at a stroke provide an alternative network to Whatsapp available on every phone and desktop.

Apple is currently resistant but I think they'll come round to the idea once they realise that that they can pretty easily displace Meta from day to day messaging.

Hmm. Think you could be right. Question to me is whether they can provide anything compelling beyond stability of identity / ease of connection. That would itself be pretty huge though, so is maybe enough to displace WhatsApp and the like.
