Singularity Part X: ZettaFLOPS in the Void
xAI’s Colossus 2 is now operational—a gigawatt-class behemoth with over 550,000 NVIDIA Blackwell GPUs, delivering more than 1,000 exaFLOPS of AI-optimized compute. This torrent of power consumes around 1 GW, enough to energize a major

As humanity taps into the Sun’s vast energy, the next leap is building the infrastructure to harness it: automated factories orbiting Earth, the Moon, and beyond.
Space offers zero gravity, abundant vacuum, and endless solar power—ideal

Speed of light means latency is always a factor, even on Earth.
But we already know that small intelligence computers with insanely high latency and packet drops (aka humans) can build all of civilization, so latency is not a fundamental scaling constraint.
You just have to do localized buckets of compute that pool and synchronize their output to work to a greater goal.
