Lochmiller is the co-founder and chief executive officer of Crusoe, a startup that helps develop AI data centers. Crusoe’s costs to build the one in Abilene are expected to reach about $12 billion, Lochmiller says. And that’s not counting the billions of dollars’ worth of Nvidia Corp. chips that will be installed in the finished facility. “I’ve never built anything of this scale,” Lochmiller says. “I’ve had to learn a lot on the job.”
