  I am not a number! I am a free man!
  I will not make any deals with you.
  I've resigned.
  I will not be pushed, filed, stamped, indexed,
  briefed, debriefed, or numbered!
  My life is my own!

You speak as though advertising was for you.

The data being collected about you is used to sell you to advertisers, and your data to 3rd parties.

you see advertisements not because you are interested in a product, but because the seller of the product is interested in one of your characteristics (like your income, sex, weight, religious affiliation, price insensitivity, poor decision making skills, etc...)

1. I think is far from established, and if anything the accumulating evidence shows the opposite (though I do hate the term AI when used like this)

2. The issue (for me, at least) is not "AI" replacing human equivalents (though in some parts of life, this is a huge issue), but rather the ease to which the AI's actual purpose and success metrics can be different from the claims made about it by its owner-operators.

It's not that this can't happen with human beings too - financial advisers who are actually lining their own pockets rather than providing you with the best advice for you. But it is much easier to hide nefarious intent inside an algorithm, and harder to discover it without access to source code (and non-trivial even then).

Depends, I would prefer reco Algos be open source and I can plug in different ones.

Trying to make sense of the mass of data without a personalized recommendation engine is a fools errand.
