Advertising worked just fine for more than a century, ever since the invention of consumerist society. (How much of that is really necessary in a society that is pushing headlong into unsustainability is another, bigger story.)
The disaster we have now in our hands is of a more immediate and crass nature.
Think about it: there are algorithmic breakthroughs that can help everybody on the planet raise their level of information retrieval and the only discussion is which of the former or the current consumer tech oligopolies will use it best to push ads and how to double down on a bad design.
