As of April 17, the authorship for "Homo Deus" was fixed, and the list was down to 4,334. I just had a brief chat with Amazon about the whole list, asking "I would be grateful if you would contact them, and have the Amazon team begin to fix this."

Amazon replied, "Yes, definitely, I'll contact them right away and sent all the details to fix this, you will able to see the changes within next week starting as fast as possible."

I don't know how this happened, but as long as it gets fixed, I'm good.
