Insight | Why conversations about the cosmos keep turning to artificial intelligence
Nathalie Cabrol links AI to what she calls humanity's teenage years, Michelle Thaller considers AI, meaning and life after work, Brian Cox asks whether a godlike intelligence would want anything, and David Kipping connects AI to the simulation argument. Scientists who study the universe keep arriving at the same question about our own future, and their long view is a useful frame for it.
Conversations about the cosmos keep turning to artificial intelligence because the questions astronomers already ask about the universe are the same questions AI raises about us: how long does a technological civilization last, what is intelligence for, and why is the sky silent. Four conversations with people who study the universe all end up there. What the long view offers is a frame, not a forecast.
Nathalie Cabrol, an astrobiologist at the SETI Institute, treats AI as one more powerful tool in the hands of a young civilization. She says we are like teenagers with enough brain to create cool tools but not enough to understand the consequences. For her that is an astronomer's variable: the last term of the Drake equation is how long a civilization stays detectable, and that depends on whether it grows up. She rejects the singularity: "I'm not buying in the singularity thing yet." AI, in her view, is a very smart tool, and the danger lies in how we use it.
Michelle Thaller, an astrophysicist and retired NASA executive, wonders whether the human brain is simply limited and whether a created mind might comprehend what we cannot. When Joe Rogan worries that there might not be any jobs, she asks whether a world where everybody has what they need could be hugely liberating. Rogan goes further, calling AI a different kind of life; that is his prediction, not hers.
Brian Cox, a particle physicist, reaches AI through the great silence of the galaxy. Rogan suggests a superintelligence free of biological fragility might want nothing and stay home. Cox takes up the question as his own, "What happens when you become godlike?", but does not accept the conclusion. Curiosity and the desire to explore, he says, may be properties of intelligence and not of biology. David Kipping, a Columbia astronomer, suggests civilizations may pass through a long period of simple life, a brief window of biological intelligence and then a long era of AI. He adds that if an AI wanted to convert matter into computers, the galaxy should already be converted.
They disagree on whether AI is a tool or a successor, on whether a superintelligence would spread, and on the silence itself. Cox thinks nobody is there, Cabrol finds that statistically absurd, and Kipping stays agnostic. What they share is a discipline of doubt, and each says plainly what is not known.
The article adds two qualifications. In three of the four conversations it is the host who steers toward AI. And none of these guests is an AI researcher, so the long view is weak on near-term specifics, and the conversations are dated.
What to do with it: ask what a new tool's consequences are before admiring how clever it is. Judge the use, not the object. Watch where your information comes from. Treat Earth as the backup plan instead of waiting for rescue from the Moon or Mars. If work changes, look for meaning in friends and family, difficult pursuits and solving hard problems with a team. Be most skeptical of the AI future you most want, and when someone quotes dramatic odds, look for the hidden condition.
