No, it's somewhere in between.

"I want to visit this movie theater, but they require me to drive 20 miles out of the way for a ticket, in to a dodgy neighborhood where I could get robbed and raped, when I could just walk in the door instead."

Websites did this to themselves. The fact they don't require the ad networks, or even punish them in any way when their users are harmed is what caused this situation.

This isn't a mechanical problem, it is a vision problem. Humans miss spots while cleaning all the time, but we have one advantage, we can easily tell what is and isn't dirty, then we go back and correct. The issue I see is we aren't solving the vision and object recognition problem for some time yet so humans will still have that advantage.

Studied some oceanography. The problem is not that beaches are transient. The problem is our idea of property. The problem is ports, seawalls, jetties. We want beach front property we can have a house on, a hotel on, a strip mall by. You can repair a beach. Just quit building within a few miles of it. It's a moving object. It will show back up once you give it the proper habitat. If you build houses and seawalls up the entire coast you will not have beaches. That means the beach disappears. The natural mechanisms that make beaches cannot do their jobs.

No, not exactly. Doing that you end up with very small, sharp, broken rocks. You also end up with a chemically active surface, depending on the type of rock, that is very alkaline or acidic. Sand (at least beach sand) is both mechanical and chemical weathering of rocks that is then polished by water over time.

This is pretty much it.

While my main job is working on computers, I do like researching other things. I've read a few books on beach engineering and coastal erosion. Here's pretty much what no one who owns beach property is going to want to hear...

"If you want a beach, you can't build anywhere close to it".

Sea walls that protect houses prevent beaches from forming and they will erode up to the wall. Piers change beach dynamics and where there was once sand, there will quickly be nothing (or in some cases the beach will advance very far out the pier ruining its intended purpose. The beach is a very dynamic place and anything you put out there changes those dynamics.
