"AI" (and don't get me wrong I use these LLM systems constantly) is off the charts compared to normal data centre use for ads serving.

And so it's again, a kind of whataboutism that pushes the scale of the issue out of the way in order to make some sort of moral argument which misses the whole point.

BTW in my first year at Google I worked on a change where we made some optimizations that cut the # of CPUs used for RTB ad serving by half. There were bonuses and/or recognition for doing that kind of thing. Wasteful is a matter of degrees.
