the TLDR is that the current historic peak supply of the texas grid is around 100gw. The queue of datacenter demand is 460gw.

If the new capacity uses gas to deliver the power it will consume more gas than the USA exported last year.

So basically it will drive up costs _globally_ to a comic scale, for limited return (its already expensive to train new models, this will make it ruinously expensive to both train _and_ run)
