But it isn't even a problem that experts don't know how to solve it. We know how to solve this issue. The problem is that at basically every large company someone's bonus is tied to keeping the current status quo. There are all these measures and statistics around ad revenue and spending, but the problem is that a lot of it is naïve and outdated, but nonetheless John's quarterly bonus is tied to a program that is defunct and wasteful, and often these are business people, they are not going to blatantly work against their own interests.
It is like with Google. They have a huge issue with the company spinning up new projects and then abandoning them at the drop of a pin, and it is crystal clear why this happens (people take on impactful[i.e. visible] projects for their promotion packet, but the incentives are for heading a project, not for maintaining it). It isn't a matter of figuring out a solution, the problem is that the problem will persist as long as important stakeholders are financially incentivized to resist change.
