I can't wait for AI to become the ultimate ad-removal tool.
There might be an arms race, but the anti-ad side will win as long as there isn't a unilateral winner (strongest models, biggest platform).
There will be enough of a shake up to the current regime -- search, browsers, etc. -- that there is opportunity for new players to attack multiple fronts. Given choice, I don't think users will accept a hamstrung interface that forces a subpar experience.
We basically just need to make sure Google, Microsoft/OpenAI, or some other industry giant doesn't win or that we don't wind up living under a cabal of just a few players.
I'm already hopefully imagining AI agents working for us to not just remove advertising noise, but to actively route around all of the times and places we're taken advantage of. That would be an excellent future.
