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.

New Horizons is now *three days away* from shutting off its two heliophysics instruments, simply because NASA has not provided the $2M in funding it had promised to the mission last year or this year. There is no science basis for shutting these off. Our earlier coverage:

I like the simple "something big that it is still bigger than" approach, like human energy use. Or something physically related like the scale of temperature increase if that energy were added to the atmosphere rather than the ocean. (Another way of getting at 90% going in the ocean, but still.)

Why this comparison? It's interesting to think about the lifecycle analysis of exporting materials to space or importing materials from space. Also, I figured the Venn diagram of AI megaconstellation bros and asteroid mining bros was an ellipse with an eccentricity of zero.

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.

I was curious, so I ran some numbers on the metals we'd lose by launching a giant AI data center constellation into space where they can't be recycled. I was still curious, so I figured out how big of an asteroid you'd have to mine for an equivalent amount. www.sjon.earth/launching-or...

Launching orbital data centers is like asteroid mining in reverse
How much e-waste material would be lost by putting AI data center servers in space, instead of a building where they can easily be collected and recycled?

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.

For my first story (no paywall), I dug into whether there might possibly, maybe, on the off chance, be some environmental hazard associated with Elon Musk's proposed orbital AI data center satellites constantly burning up in Earth's atmosphere.
