I was very influenced by Jakob Nielsen's books and writings at useit.com, but he's totally gone off the deep end since selling(?) NNgroup.

He is dearly in need of an editor. There's probably some useful insight in there somewhere, but his writing is way too long and absolutely full of every type of AI generated media (even including cringe music videos: https://www.youtube.com/watch?v=3WDK-YYbLYg).

It's sad to see.
