LLMs need to burn significant amounts of power for every inference. They're exponentially more power hungry than searches, database lookups, or even loads from disk.
I.e., they are proud to have never intentionally used AI and now they feel like they have to maintain that reputation in order to remain respected among their close peers.
But I do derive value from owning a car. (Whether a better world exists where my and everyone else's life would be better if I didn't is a definitely a valid conversation to have.)
The user doesn't derive value from ads, the user derives value from the content on which the ads are served next to.
The value you derive is the ability to make your car move. If you derived no value from gas, why would you spend money on it?
If they just wanted ads blasted at them, and nothing else, they'd be doing something else, like, say, watching cable TV.
If they want LLM, you probably don't have to advertise them as much
No the reality of the matter is that people are being shoved LLM's. They become the talk of the town and algorithms share any development related to LLM or similar.
The ads are shoved down to users. Trust me, the average person isn't as much enthusiastic about LLM's and for good reasons when people who have billions of dollars say that yes its a bubble but its all worth it or similar and the instances where the workforce themselves are being replaced/actively talked about being replaced by AI
We live in an hackernews bubble sometimes of like-minded people or communities but even on hackernews we see disagreements (I am usually Anti AI mostly because of the negative financial impact the bubble is gonna have on the whole world)
So your point becomes a bit moot in the end but that being said, Google (not sure how it was in the past) and big tech can sometimes actively promote/ close their eyes if the ad sponsors are scammy so ad-blockers are generally really good in that sense.
