I missed this Pew study in August, but was just pondering what this number is up to. This is what an extinction event for the information ecosystem looks like. www.pewresearch.org/data-labs/20...
Timeline chart since 2023, showing new pages climbing to 35% and all pages climbing to 9.6%.

Paragraph reads: In the July 2026 snapshot, signs of AI authorship can be found in over one-third of pages published after ChatGPT was released. This is in line with other studies that have shown that large shares of recently published pages on the internet were likely written or substantially edited by AI.

Even with an *extremely* conservative estimate, I was pretty surprised by how big some of the numbers get. This is all *per year* by the way, because we're talking about 200,000 satellites dying annually.

Ozone depletion has started to get some research attention in the context of Starlink, OneWeb, etc. The data center constellation would be much, much bigger. Makes ya think!
Screenshot from the article:

A 2024 paper can help us relate this back to the AI data center satellites. That team modeled the process of a Starlink-sized satellite burning up on reentry. They estimated that a 250 kg satellite would release about 30 kg of aluminum oxide nanoparticles ready to deplete ozone. Given that, they estimate that satellites would have released about 2 metric tons of aluminum oxide in 2016, increasing to almost 17 tons in 2022. When megaconstellations like Starlink reach steady-state operation in the future, that number could be around 360 tons.
For comparison, the total amount of aluminum in small meteoroids entering Earth’s atmosphere each year is about 140 tons—the amount oxidized into similar nanoparticles would be some fraction of that.
If we use these numbers as a rough estimate—30 kg of aluminum oxide particles from a 250 kg satellite—we can scale it up to the proposed AI data center satellites. Each of SpaceX’s “AI1” satellites are expected to come in around 6 tons. (See Eric Berger at Ars Technica for the working on that. Although Elon Musk also helpfully noted that they are “very, very tiny compared to Earth.”) That would mean 720 kg of aluminum oxide nanoparticles released per satellite. With 40,000 to 200,000 of these satellites reentering Earth’s atmosphere each year, we’re talking 29,000 to 144,000 tons per year.

Screenshot from story: Most streamers don’t go out of their way to label AI music, but Deezer has worked to develop technology to identify that content. In a recent update, the company says AI music is approaching half of all new uploads, and most of the supposed listeners of those streams are AI themselves.

In what world would a language model ever be applicable to something like this? You might as well be saying that we're all at risk unless the military gets a Furby in every cockpit. www.washingtonpost.com/technology/2...
A defense official said the Pentagon's technology chief whittled the debate down to a life-and-death scenario at a meeting last month: If an intercontinental ballistic missile was launched at the United States, could the military use Anthropic's Claude AI system help shoot it down?

Cool.
In fact, harnessing even a millionth of the Sun's energy would be more than 10,000 times more energy than human civilization uses today.

Building those power plants and launching them into space isn't challenging?
Global electricity demand for data centers is projected to more than double by 2035 driven by growth in AI ― reaching approximately 1,200-1,700 terawatt hours and accounting for up to 4% of total worldwide electricity consumption. Building power plants and other terrestrial energy infrastructure at scale to maintain this additional power continuously on Earth will be extremely challenging.

Low operating costs because it's solar? You could do solar on Earth. Low maintenance costs because... it's impossible to ever touch it once you launch it.
By directly harnessing near-constant solar power with little operating or maintenance costs...

The document (linked in the story) has a lot of silly in it.
Launching a constellation of a million satellites that operate as orbital data centers is a first step towards becoming a Kardashev II-level civilization―one that can harness the Sun's full power―while supporting AI-driven applications for billions of people today and ensuring humanity's multi-planetary future amongst the stars.
