"Will tech giants move on from the internet, now we've all been harvested?"

The title is a pernicious exaggeration. They have not got data about all of us; for instance, outside of a few areas, the databases have little information about me. And I hope you too have resisted.

But that doesn't invalidate the idea of the article.

I am skeptical that there will cease to be companies with a hunger for data. There will occasionally be new competitors that want the data that other companies already have. There are fields in which they don't have enough data. Beyond that, they would like to understand every individual, and individuals change.

Notwithstanding that, the projected change may happen to some extent.
