That's because, I believe, cosmically connected societies are, essentially, floating planet sized brains. Their living beings are basically the cells of this organism, and networks of roads, data lines and such are the connective tissue linking the neurons that exist as beings of that planet.
At some point in our future, we'll all be a unified race of people working towards not only the betterment of the planet, but towards the ability for this giant floating spherical brain to reach out to other giant floating spherical brains using methods of communication that can only exist at the planetary scale.
By that time, humanity will be unrecognizable for us. People would be as different from normal folks now as those on the autistic spectrum are. We're evolving, the planet is evolving, and on the cosmic scale, it's the only logical explanation for why the universe seems empty: it's not that there aren't other civilizations, it's that they're essentially so different in scale from us when they reach the galactic phase of growth that we will not be able to tell the difference from a planet-sized brain and a regular planet.
Additionally, the size of the cosmos hammers home the idea that ant-sized being such as ourselves hoping to navigate the universe is simply silly and we shouldn't be much concerned beyond our solar system for a good million years or so.
We can pick this UFO thing back up when we're all one unified peoples across the globe with a single purpose. I will additionally bet that there's about a 99% chance that such a society would be ruled by computer overlords. I'd be OK with that, actually, as we've REALLY fucked things up using people as leaders, recently. I cannot imagine saying that 20 years ago, but here we are.
This will all probably start to happen in earnest (these changes to humanity, I mean) sometime after we install dictators to deal with the climate change problems which we allowed to get utterly out of control to a point where the only solution will be utter dictatorships and violence and instant death for anyone who damages the planet. It'll REALLY suck, but we will hopefully come out the other side with fewer opportunities for greedy people to direct entire civilizations to memorialize their greatness in blood.
