Musk wants to put up 500-1000 TW per year. Even 1 TW would be 4.348 million of your systems. Even one of your clusters is at the edge of what we've built, and you talk about snapping 4000 of them together as if they were legos.

To run just one cluster (which would be generally a useless endeavor given it is just a few dozen GPUs) would be equivalent to the best we've ever done, and you wonder why you're being downvoted? Your calculations, which are correct from a scientific (but not engineering) standpoint, don't support the argument that it is possible, but rather show how hard it is. I can put the same cluster in my living room and dissipate the heat just fine, but you require a billion dollar system to do it in space.
