this is an announcement not a cut check. Who knows how much they'll actually spend, plenty of projects never get started let alone massive inter-company endeavors.
The $100B check is already cut, and they are currently building 10 new data centers in Texas.
A state with famously stable power infrastructure.
$50B is to pay miners not to mine.
because you put your own people on the receiving end too AND invite others to join your spending spree.
