In fact it's apparently $5.2 trillion by 2030 [0] (out of $6.7T total data center spend; meaning all of "traditional IT needs" are less than a quarter of the total). That's the total if you add up all of the firms chasing this opportunity.

I do wonder, if you (and the commenter you replied to) think this is a good thing, will you be OK with a data center springing up in your neighbourhood, driving up water or power prices, emitting CO2? Then if SOTA LLMs become efficient enough to run on a smartphone will you be OK with a data center bailout coming from your tax dollars?
