Unrelated, but you remind me of how absolutely useless ad technology is. The literal second I cross the border into Spain on holiday all I see is completely Spanish ads for stuff I never heard of and aren't even appropriate for my gender. This is for a ten year old YT account that basically knows everything there is to know about me. Even when I continue and look for English videos they keep shoving Spanish bullshit into my face.

Even at home I still get ads for music festivals, shoes and toothpaste, none of which are withing a thousand yards of my personal preference. The times I saw an ad for mechanical keyboards, interesting APIs, IDEs etc I can count on literally one hand and that's being online for decades.

iPhones' builtin autocomplete, Netflix and Spotify's recommendations all have robbed me of the illusion that smart people are actually working on this problem. If they are, it ain't working. The money printer works but not because of clever tech. YT's ad tech basically boils down to a geolocation of IP and I sometimes even question that.
