Regulation. It's a harsh measure, but I doubt there is another one. The last 20 years people tried to find alternative solutions. We have pay-walls, we have crowdfounding, we have various subscription models, I fail to see a solution that hasn't been tried, but yet every single year we get exposed to more ads. It seems extremly unlikely that there is something that could replace ads.
But what is the logical solution when there is a damaging thing in society that can't be replaced by healthy alternatives? It's regulation.
Now I know that a ban on ads seems unlikely. But I honestly don't think we have a choice. Because the alternative is that the ad-industry keeps creeping into every single aspect of our lifes, like they have done ever since their emergence. And with the advance of AR, smart homes and AI assistants this seems like a bad idea.
