Targeted ads should be illegal.
Contextual ads are a compromise I would accept. That is, you can buy ads based on the page content, but not the viewer details. So if I’m looking at a website about bikes, you can have bike ads on there. You don’t need to know I’m a xx year old living in zip code 10001. That’s how ads worked for like decades (centuries?). It’s fine.
There was a (fiction) book I was called “all the birds in the sky”. I really liked it. Highly recommend.
One of the plot threads is a rich tech bro character that’s like “the world is doomed we need to abandon it for somewhere else. Better pour tons of resources into this sci-fi sounding project”. And I’m just screaming at the book “use that money for housing and transport and clean energy you absolute donkey”.
There are a lot of well understood things we could be doing to make the world better, but they’re difficult for idiotic political reasons. Racism, nimbyism, emotional immaturity, etc.
