> I guarantee you that in the next five years there's going to be a huge exodus out of the incumbent networks

Are you willing to change your mind on this?

What evidence do you have this will happen?

It does seem that social networks can have some generational stickiness. Wrestling my family away from Facebook feels like a lost cause. But younger relatives are more active on Instagram and some other options.

But I don't see what would trigger an exodus given that everything you and I might not like about the existing social media incumbents hasn't been enough to drive people away en masse so far.
