Yes, our entire civilization is built on trust relationships. Trust relationships are easier to succeed when the interests of the two parts are aligned, or at least mostly aligned.

The ad business model guarantees that our interests are misaligned. I don't want to depend on intelligent agents that want to sell me things, and I don't think anyone with half a brain would either. The more intelligent they are, the more one should fear being manipulated and spied upon if one those not control them.
