I understand location is important for web/traditional data centers but why do they put these AI centers so close to people? Could they not put them somewhere far away like maybe in the middle some Nebraska farmland where it's just miles and miles of corn everywhere or the desert? I guess water would be an issue but it's closed loop no? Couldn't they just truck in the water and re use it or something?
