Attention based models are still extremely data inefficient and fail to generalize. I recommend reading the "On the Measure of Intelligence" paper by Chollet if this topic interests you.
I could actually see a use case for web scraping. If you're after particular pieces of content that aren't accessed in a structured way, on a site that rate limits you to the point of being restrictive, maybe using a bit of NLP could help you rank links to click.
I disagree with this so much. Data is used for far more than ads. If you can't collect data but your competition can, they'll run a more efficient business, offer better products and be more adaptive to change.
