I can't make a case for AI versus not AI versus bad human. I am not counting comments or flagged. I'm only counting the number of new articles in the last 24 hours that remain visible at about 4p.m. west coast time in news.ycombinator.com/newest when not logged in to yc. Those numbers had been consistently about 900 each weekday and about 600 each weekend day and had been stable for a long time. In the last ten weeks those numbers look a lot like a parabola and have increased about 50%. That data is a little bit dirty, either because I missed a day or started a little late on a day. Harder to exactly quantify, the number of those articles that I think enough of, either from the title alone or sometimes from peeking at the first screen or two of the article, to bookmark for future reading and consideration has decreased by substantially more than 50% in the last ten weeks, some days that number is now zero or one or sometimes two. I have thought about this for a while and I have not been able to identify anything that happened starting about ten weeks ago that might be responsible for this, AI and politics and the economy started changing long before this.
