Ads aren't a long-term viable model for tools. Each year it gets more feasible to self host tools (email being the od exception, but there are still many ad free alternatives). Ads shifting vehicles to AI will extend the lifetime a bit, but even still local models are getting better and that's without even much architectural advancement.
I don't see an end to advertising all together though, public spaces and entertainment don't really have an escape unless forced by regulation.
