| "... (no add trolls please, it's just an example)." What is an ad troll. Is it like someone who believes advertising revenue "makes our modern world spin".^1 1. https://news.ycombinator.com/item?id=29186326 That is interesting because advertising spend is probably one of the least certain investments. It's causal effectiveness online is difficult if not impossible to measure. It is like suggesting casino receipts are what make the modern world spin. Adtech is, IMO, not a "major path to innovation". Unless one adopts a very narrow view of what innovation looks like. It is wonderful to hear someone claim "I want to do X, but I have to do Y to feed my family", where X is "something important to the world" and Y is not. However, if doing Y is diverting attention away from X, or possibly even causing harm, then maybe "not doing Y" is also "something important to the world". No doubt people working for companies who were selling massive quantities of opioids were feeding their families, and arguably they were not violating any laws. Unfortunately, these criteria were not by themselves enough to stop them from doing harm. |
