Democracy cannot survive overpopulation. Human dignity cannot survive it. Convenience and decency cannot survive it. As you put more and more people into the world, the value of life not only declines, but it disappears. It doesn't matter if someone dies.
The energy requirements for interstellar travel are so great that it is inconceivable to me that any creatures piloting their ships across the vast depths of space would do so only in order to play games with us over a period of decades. If they want to make contact, they would make contact; if not, they would save their energy and go elsewhere.
Interpretation
What this quote means
The quote suggests that if extraterrestrial beings exist, their reasons for traveling through space would be more significant than simply trivial engagement with humanity.
Isaac Asimov's quote reflects on the immense energy required for interstellar travel and posits that any advanced civilization capable of such feats would likely have serious purposes for their journeys. The idea that they would only engage with humans for entertainment or trivial matters seems implausible; rather, if they were truly interested in communication, they would readily make contact, or alternatively, they would conserve their energy for pursuits that matter to them elsewhere in the universe.

Although the time of death is approaching me, I am not afraid of dying and going to Hell or (what would be considerably worse) going to the popularized version of Heaven. I expect death to be nothingness and, for removing me from all possible fears of death, I am thankful to atheism.
A subtle thought that is in error may yet give rise to fruitful inquiry that can establish truths of great value.
During the century after Newton, it was still possible for a man of unusual attainments to master all fields of scientific knowledge. But by 1800, this had become entirely impracticable.

The problem with data is that it says a lot, but it also says nothing. 'Big data' is terrific, but it's usually thin. To understand why something is happening, we have to engage in both forensics and guess work.
The art of doing science is doing the important things first.
But our ways of learning about the world are strongly influenced by the social preconceptions and biased modes of thinking that each scientist must apply to any problem. The stereotype of a fully rational and objective scientific method, with individual scientists as logical (and interchangeable) robots, is self-serving mythology.
I won't compare ants and people, but ants give us a useful model of how single members of a community can become so organized that they end up resembling, in effect, one big collective brain. Our own exploding population and communication technology are leading us that way.
We have language and they do not. Chimps communicate by embracing, patting, looking - all these things. And they have lots of sounds. But they cannot sit and discuss. They cannot teach about things that are not present, as far as we know.
Almost any questions can be answered,cheaply, quickly and finally, by a test campaign. And that's he way to answer them - not by arguments around a table
