I'm getting concerned about this "feedback culture" that's been developing over the years. Now Amazon wants me to rate deliveries and tick checkboxes... Delivered with Care, Above & Beyond, Followed Instructions, etc. It was a package, it was delivered, I'll let you know if I had any complaints. My big fear is that every time someone wants me to rate an individual person's performance (restaurant server, Lyft driver) that their job is on the line. Therefore I lie in my ratings.
But there's another thing about Harry Potter... the story can be frustrating because of how unfair Harry's world is. Why does the school employ a janitor who hates kids and is out to get them? And it struck me on this read-through that this is the world through a tween's eyes... teachers are out to get you, they have favorites who can do no wrong, the rules are applied unfairly. It's a world of being powerless to defend yourself against those in power.
Rereading Harry Potter and one thing that strikes me... they're essentially mysteries, but the clues just aren't there. There's lots of misdirection, but there isn't enough information for the reader to figure out what's really going on. Is that intentional? Wanting the big reveal to be a surprise the reader didn't see coming, so the lack of clues is on purpose? I suspect so.
@CarlCravens Clearly when people buy a wing-brake the algo has noticed they subsequently need repair parts for vehicles they don't even own.
It's Amazon's daily recommendations that convinces me machine learning combined with detailed info about me isn't _too_ dangerous yet. Today's recommendation was a 100 pack of automobile fuses. They regularly offer me parts specific to vehicles I have never owned (and I've told them what models I own). I bought one thing related to a car (but not a repair part) six months ago.
