@andresmh you may well be right. Sigh.
And in one sense, people are free to do whatever they want, and if people no longer want those networks, we can't force it.
But also academia, journalism, & civil society seem less connected now than any time in the 21st century. That seems substantively risky, for society & for the next generation. I fear we'll lose the richness of knowing each other & sharing inspiration/ideas effectively.
So I'm looking for what I can do about this, with others.
