Even if you showed me the perfect ad, I probably would not buy it. Because if I need it, I probably already bought it, and if I don't need it, I won't buy it. So there is not much money being made, ergo we get shown ads for the other type of person.
And as much as I hate that this is what is happening, I feel like that's what I'm going to end up being forced to try after 15+ years in working software development jobs, given how badly the companies want to replace us with LLMs. Hasn't gotten to that point yet but I'm shocked every day we're not laid off.
Presumably these ads are targeted intentionally to their audience, and this research confirms it.
