Most of it escapes into space. It's gone. You can make some more by fusing hydrogen atoms.
We will never have "real" AI because every time we approach it, someone moves the bar as to what is required.
Artificial bars. The requirement is simple, have a computer that thinks like a human.
You don't even know what algorithm the human brain uses. They didn't in the 80s, either. Figure that out before you complain about bars being moved.
Sounds like it. Apple and 5 publishers tried to raise the price of new "e-books from the $9.99 price that Amazon had made standard".
So why does Amazon get to set the price, and not Apple or the publishers?
This is so simple I'm amazed you got voted up. Fundamental market mechanics is that sellers try to raise the price, buyers try to lower the price. Everything from someone haggling over an item at a flea market to a multi-billion dollar corporate buyout operates this way. Both buyer and seller are acting in their own interests. However, the counterbalance to sellers having the power to raise the price is that if they raise it too much, buyers can go to a different seller to get the same or similar item. That natural balance between sellers trying to get as high a price as they can without driving buyers to competitors is what sets the market price.
Apple and the publishers were sellers who tried to raise the price. If they'd arrived at that price individually, then there's no problem. But they colluded to set it at that price, which is absolutely illegal since it breaks this fundamental market mechanic.
Amazon was a seller who tried to lower the price. That's not a problem since it benefits the buyer. It's just like a store deciding to hold a sale. (There's an anti-trust argument that Amazon shouldn't be selling ebooks at a loss, using profits from other markets to undercut competitors in the ebook market. But that wasn't the focus of this particular case, and its disingenuous to try to argue Apple and the publishers aren't guilty because of this. Both can be illegal. If Amazon's ebook pricing is driving competitors to bankruptcy, then that's a separate issue that needs to be decided in a separate case.)
That's it? Seriously that''s not enough for many people.
That's why many people aren't working on it.
But for people who do enjoy that kind of thing, it sure beats watching TV or hanging out at a bar.
