Joe Hansen(@joehansen):4 days from bare slab to steel standing. That's how fast SpaceX is building its new AI data centers. SemiAnalysis says only 1 in 5 big AI data centers gets built in under 2 years. At SpaceX's Brownsville site, aerial photos showed the steel going up 4 days after the slab. The new one in Memphis is called Minihard. Elon says it got the name for being half the size of Macroharder, and then they doubled it. It will hold about 220,000 Nvidia GB300 chips, which DCD says likely needs more than 400 MW. This morning Elon said SpaceX tried to rent inference compute from AWS, Google or anyone. Same story as 2002. Elon went to Russia to buy a rocket, they didn't take him seriously, so he decided to build his own.
