Seriously, the moment an ad pops up, I'm looking for the close button. I don't pay any attention to the advertiser and if I do, it's usually an automatic negative impression.
It's a numbers game. While the industry buys and sells impressions, only a tiny percentage of people actually buy things. Why in the world can't THE TYPE OF PERSON that tolerates online advertising be their target, instead of the rest of us innocents?
You ever take a taxi or Uber and have the radio blaring, including commercials (which last many minutes at a time, sometimes a huge percentage of the ride)? I have, in fact most of my car rides. THAT is the type of person that tolerates ads.
If the entire ad experience were opt-in, maybe they could charge higher for impressions. Those impressions would actually matter, because the chances of trying to forcefeed and forcibly distract a concentrating nerd reading a news or tech article and the latter getting annoyed would be much smaller.

Your brain is automatically filtering stuff out because if it didn't you'd go crazy. Just imagine remembering everyone's face you saw on your commute or every conversation you had at that party last week.
No for real, I think banner blindness is an automatic attempt to solve the real problem: intrusive unwanted and even dangerous ads.
