So it's about technology, technology that we can actually capture from space.

You become visible to your neighbors.

And this is all about the Fermi paradox, right?

It takes time.

Obviously, if we're taking, again, ourselves as a model, but this is the only one we have, right?

to get to the point where we become detectable.

But look at the age of the universe.

Even if life as we understand it, not saying even as we know it, but as we can understand it, started 10 billion years ago.

And it takes 4 billion years to get to the point where it becomes detectable.

That means that the first planet where those civilizations started off, starting to be detectable when we were still cyanobacteria in pond.

So they were, you know, throwing messages that were passing above our heads at that point.

And those civilizations, when you look at them now, close to 10 billion years after the start,

So their son would be dead, okay?

In the best case scenario, they move somewhere else.

And what that means is that civilizations are going to rise, die, or move and transform themselves.

We can see ourselves changing.

We know that humans are still changing as a species.

The human being in...

in a thousand or even 500 years from now.

It might not be looking a lot like we are doing right now.
