Starcloud (@Starcloud_Inc1) recently made history by launching a satellite with an NVIDIA H100 into orbit — the first time a GPU that powerful has ever operated in space. It's the first step toward building AI data centers in orbit, powered by continuous sunlight and cooled by

Second prediction, the algorithm will start to aggressively down rank AI content. In future to get engagement will be to be maximally human: - was it slowly typed into a text box at 1:57am ✅ - does it reveal something embarrassing ✅ - was it posted incorrectly and then

Among the other things AIs will get better at is recognizing AI-generated text. Presumably writing generated by this year's models will be easy to catch in a few years. Prediction: This will cause huge scandals in academia, as published papers are later exposed as AI-generated.

Without space datacenters we're on track for a Grey Goo type doomsday scenario, where every square meter of earth's surface gets tiled by solar + datacenters. Once AI is unconstrained to expand out into space, it makes no sense to eat up earth - we're safe.

Plots of empty desert could soon be worth more than the most fertile farmland in human history. @CJHandmer ran through the back-of-the-envelope math. 10 acres of solar is enough for 1 MW of H100s. And the FLOPS done by those H100s is roughly equivalent to 1000 human brains. If

Yep, $/kg to orbit is the only thing stopping all compute to move to space 👌

Orbital Datacenter Profitability Comes Down to One Number
The first datacenter-grade GPU in orbit was an Nvidia H100, launched on Starcloud-1 in November 2025. It was a 2022-era chip flown on a roughly 60kg (132lbs) test satellite, and it did something...
