Can Civilizations Survive Beyond 5,000 Years? AI May Be the Key.

As the current confrontation between Iran and the United States raises once again the specter of nuclear escalation, a deeper and more unsettling question emerges:

How long can a technological civilization actually survive?

For decades, nuclear war has been seen as humanity’s ultimate existential threat. Today, as geopolitical tensions intensify and multiple global flashpoints converge, it is becoming clear that this is only one risk among many.

A recent scientific analysis, discussed in outlets such as Universe Today and The New York Post, revisits the famous Fermi Paradox — the question of why we have not detected other advanced civilizations despite the vastness of the universe.

Two physicists from Sharif University of Technology in Tehran, Sohrab Rahvar and Shahin Rouhani, approached the paradox from a different angle:

What does the silence itself tell us?

Their conclusion is striking.

If intelligent life is common, then technological civilizations do not typically survive for millions of years — or even tens of thousands. Instead, statistical reasoning suggests a much harsher limit:

Around 5,000 years.

This places humanity in a uniquely fragile position.

We have been a technological civilization, in any meaningful sense, for roughly 200 years. In other words, we are still at the very beginning of what may be the most dangerous phase of our existence.

The threats are well known:........
