Ads don't show you what you value. They show you what companies think you will waste your money on. You need to wake up, my friend.
Taking money to decide which of the options to show is in conflict with the goal of showing the most appropriate.
This is a deep kettle of fish to be opening, but I don't believe that the world we have constructed around us is necessarily good for us.
And ultimately, while yes your examples are modern services that provide us convenience and entertainment, at a deeply human level I still argue that they are not providing net positives to us. Bread and circuses.
But on the other hand I'm almost certain I wouldn't have pushed through and gotten a degree without the internet (3b1b and Khan Academy in particular). I don't know what the world would look like without Google so almost impossible to argue, but I would definitely classify (ex. youtube) as "clearly useful".
Ad is the negative, and the services are the positive.
I am not convinced,
I would like all AI be required to state who they are acting in service of (with the possibly of declining to answer).
AI should act, To the best of their ability in the interests of who they are in service of.
It should be illegal to deliberately configure an AI to act against the interesta of whoever they are acting for.
