Now it seems like ads are driving everything. (Sure, including ads on porn, but I highly doubt porn dominates the ad market overall.)
It seems like the widespread adoption that drives and is driven by technological progress always comes down to catering to some base urge. I guess if you zoom out, everything is driven by base urges, just more or less directly?
So far, the puzzle pieces have always been found in the filthy heap of slop the feeds our primitive brains. We have not yet elected someone because they're the wisest, best fit for the position. It's always the person who can stroke our egos and soothe our fears, who lies with a smile that we choose to trust even when we know it's a lie. It's always a lie. We buy the product that makes us feel best to buy. Sometimes these happen to momentarily coincide with our best interests, but usually not, and never after the competition for our eyeballs and gonads has been minmaxed. Rational superiority is never the deciding factor—even when we convince ourselves that it is, it's that conviction that makes us feel good and determines our action.
