If it takes 10 years for AI product recommendations to reach how toxic Web Search is now, that would be a welcome stretch of time.

I think needing 10 years to get to that point is way too optimistic

There's really no need. I was looking for an Android app for a particular purpose, and Claude just regurgitated the app's marketing page, including the claim about Play Store ratings (which was wrong or very outdated). Getting into the pool of products might be a bit harder and you might need to set some some organic looking influencer blogs and such. More fuel for the dead internet.

There are ways to inject biases in a model by applying weights at different transformer layers.
