And what would the advertisers do next?

That would just further the arms race.

I don't think so. If a really smart AI cannot detect the ad, why would a user be able to consciously detect it?

AI will perhaps push ads into the subconscious space. But an arms race will make ads more and more subconscious, until they basically disappear.

Well... So what? I mean, just because an arms-race exists doesn't mean participation is futile or counterproductive.
