What surprises me is that this is state of affairs for Google, a company with unlimited budget - to show you ads for things you expressed just a slightest interest in or have already purchased. And it's a state for a loooooong time.

Like - I just purchased some plants from Dibleys, a plant nursery in UK. I've gotten confirmation email to my gmail account. Now I'm served plant ads for that very same company. I'd expect that The Algorithm would be smart to decide "hey, here is a guy that is interested in plants, let's take a look at other people in his age group and occupation, what are they also interested in, and let's serve him ads for that. Or having failed that ads for other plant nurseries in UK". But no! It's astounding, that it's so utterly mindlessly stupid.

But you know what, actually I prefer that there's no computational effort here. Maybe this means that me being served a shitty ad for a company I like and already know will not attribute to global warming. Maybe this means that Dibleys isn't being charged for a clickthrough, but for impressions that cost a lot less. Maybe this cyclical stupidity is something that we're stuck with as a human race, because why the fuck should an ad serve some kind of purpose.
