It's great at showing explicit ads or "content marketing" ads-that-land-in-it-without-paying-Google-directly.

On the other hand you have the whole of humanity's ingenuity trying to make money for themselves.

Why do we think one system is going to be able to defeat the whole universe of creative hacks to try to beat that system at any reasonable rate?

(It's a wonder that it's even still adequate... but as long as the main competitors are using the same machine-and-math-driven approach, just with fewer resources to throw at it, it's unlikely that there will be a ubiquitous replacement making a major improvement any time soon.)
