"That’s why building a product recommendation algorithm was a hot topic 20 years ago, but nowadays everyone and their mom can just get a WordPress plugin for it and get close to Amazon’s level."

Well, I haven't had a remotely relevant Amazon recommendation in 5 to 10 years. Unless you count read a book by the exact same author as a useful recommendation.

At least on my account, it seems like Amazon has given up on recommendations and is just suggesting I buy the same things again.

I wouldn't be shocked if it's actually quite a bit more accurate then real predictions, but it does lead to funny things like "You already bought this book? How about a second copy?"

I wonder if the same book recommendations are happening because people might just be buying products like these for gifts. Something like I liked this book, so you should read it to.
