Does anybody ever see relevant ads?

I guess retargeting kinda works, if I look for info about mortages I see lots of ads from banks, but for anything else?

We're all human, we're amazingly complex, everyone of us is unique, and nobody likes to be put in a drawer.

But then you have the smartest programmers in the world, working for the richest companies in the world, and all they come up with is "if someone googles for baby show them ads for nappies"?

It's remarkable how stupid these "smart" algorithms are, and I think the problem is a based on a simple fallacy: Everyone thinks of themselves as sophisticated, but believes others are simpletons.

I'm not sure where to go from here.
