Edit: And I tried to generate an article for about 10 minutes and if I didn't have any luck I would not have posted and if the post wasn't surprising then it wouldn't have been upvoted, so there's your selection bias at work. The generated text often knocks my socks off, but there's plenty of flops too.
Edit: I've hit the reply depth limit, but just to respond you you below. It is absolutely legit, though better than the average output I see and I think I got a bit lucky. If there was anything that would convince you, I'd happily post it. Feel free to look through my HN post history. I'm no troll. My only horse in the race that you believe me is that I think you should keep playing with it and see what it's capable of instead of writing it off. This seems like transformative tech to me and I'm both excited and a bit scared. Have fun!
