You make a great point that I hadn't considered before. It's like rocket fuel! The faster you want to go, the more fuel you need. Which adds weight, so now you go slower, so you need more fuel... I want to serve a cat picture, which would cost 1/100 of a cent. But at scale, it adds up. So now I show adds that generate 1.2/100 of a cent in revenue but add .5/100 cents in serving cost, which I can optimize with user data to add an additional .7/100 cents in revenue, but which adds .4/100 cents in serving costs....
