Is AI the Great Filter?

Artificial intelligence may be civilization’s greatest tool… or its last. Could AI explain why the galaxy seems silent, or does it make the Fermi Paradox even harder?

Two South Korean companies named Samsung Electronics and SK Hynix now manufacture roughly two-thirds of the memory chips inside almost every digital device on Earth — produced inside a country whose 1953 per-capita income was lower than Somalia’s or Haiti’s

Open any device built in the past five years, look inside its memory subsystem, and the chips you find were almost certainly fabricated in one of three South Korean industrial cities — Hwaseong, Pyeongtaek, or Icheon — by one of two companies whose combined market capitalisation now exceeds $700 billion. The historical improbability of this situation is not a matter of degree but of category. Korea in 1953 did not have a semiconductor industry, a precision manufacturing tradition, an advanced engineering workforce, or the kind of capital markets that could finance industrial development. It had a per-capita income lower than essentially every other country whose subsequent economic trajectory has been studied by development economists, a primarily agricultural economy substantially destroyed by three years of active warfare, and a small population (~20 million) whose adult literacy rate stood at approximately 20 percent. The proposition that, 72 years later, two companies headquartered in the same country would manufacture the memory chips inside Apple’s iPhones, Google’s Pixel devices, Microsoft’s data centres, Nvidia’s AI accelerators, Tesla’s autonomous-driving computers, and essentially every other major piece of digital hardware sold globally — would have been considered, by any reasonable observer in 1953, structurally impossible.

New Wright-Patt supercomputer calculates in a day what would take average laptop 500 years

Wright Patterson Air Force Base has a new advanced problem solver for future military systems and weapons. It’s called the Flyer, named in honor of Wilbur and Orville Wright and their research in aerodynamics.

The Flyer is the Pentagon’s latest supercomputer. It has more than 186,000 cores able to process millions of advanced calculations in a few seconds.

David Shahady, deputy director of the Air Force Research Laboratory’s Digital Capabilities Directorate, equated the abilities of this unit to a pop-culture sci-fi character.

AI isn’t a dual-use technology, it is inherently violent

When the Pentagon branded Anthropic CEO Dario Amodei “a liar with a god complex” over fears that his company’s AI could be used for weapons and surveillance, it exposed a deeper truth: the boundary between civilian and military technology no longer exists. The same systems that power translation, logistics, and digital assistants can just as easily identify targets or manipulate populations. Thomas Christian Bächle and Jascha Bareis argue that today’s AI is not simply “dual use” — it is inherently violent in design. Adaptive, autonomous, and globally networked, these machines fuse daily life with geopolitics, making peace itself a fading abstraction.

Drones have become an uncanny threat—not least in the wake of the cost of human life and the degrees of suffering and destruction they have inflicted in Russia’s war on Ukraine. In many European countries they have been sighted near critical infrastructure or military sites, either used for reconnaissance or sabotage, at times causing major disruptions in civilian air travel. Drones unsettle a population that is fearful and weary of the brutality of war at their doorstep. They have become a major element to what is labelled hybrid warfare, fought beyond the conventional ways of violence.

But this is not the whole picture. For years, drones have also been envisioned as a technology that bears the potential of bringing about major changes for the better: more efficient disaster relief, medical supply chains reaching even the remotest areas, optimized logistics or transportation. Drones also introduced a new visual – bird’s-eye-aesthetic of how to see the world.

David Brin: What’s Important Isn’t Me. And It Isn’t You. It’s Us!

David Brin warned us. In 1989.

Global warming. Cyberwarfare. The World Wide Web, named in a novel before most people had ever heard of it.

I recorded this conversation with him 14 years ago. Astrophysicist. Hugo and Nebula winner. The mind behind the Uplift novels and Existence.

We dug into the most powerful form of science fiction. Not the prophecy that comes true. The prophecy that prevents itself. Orwell’s 1984 is the classic case. The warning so loud the future course-corrects.

We also went straight at #transparency. His book asks a question that hits harder now than it did then: will technology force us to choose between #privacy and freedom? Fourteen years on, with AI watching everything, that question is no longer hypothetical.

And then there is the line from David that I have never been able to shake.

Fusion reactors could be monitored for covert plutonium production

In the next few decades, many physicists are hopeful that nuclear fusion could become a realistic source of practically limitless energy. But before this can happen, it will be critical to ensure that reactors cannot be covertly misused to produce materials for nuclear weapons.

Through new analysis published in Physical Review Applied, a team led by Patrick Huber at Virginia Tech has shown that an existing type of particle detector could be used to flag any such misuse.

US Army’s breakthrough sensor to pinpoint radio signals on battlefield

US Army scientists have demonstrated a new quantum sensor that can measure the full 3D direction of radio-frequency electromagnetic fields, a milestone that could reshape how signals are detected on the battlefield.

The breakthrough was achieved by scientists at the U.S. Army Combat Capabilities Development Command, known as DEVCOM, Army Research Laboratory.

According to the researchers, the sensor could improve situational awareness, strengthen secure communications, and help soldiers make faster, better-informed decisions in complex battlefield environments.

E= mc^2

Einstein’s famous equation has grown into one of the great symbols of the 20th century. It is the one equation in science that people recognize, if any is. It has a kind of iconic status and dual connotations: the brilliance and insight of Einstein and the darkness of atomic bombs. Images.

The basic idea behind the formula E=mc2 is easy to state. Mass and energy are really just the same thing. At first that seems impossible.

• Mass is a measure of the quantity of stuff and manifests as a resistance to acceleration. A body with little mass, like a pebble, is easy to set in motion.
