It's become somewhat of a meme, where Schmidhuber seemingly tries to claim credit for nearly everything. I _think_ it's because he published ideas back in the 90s or so that weren't fully executable/realized at the time, and later people figured out how to actually flesh them out do it, and supposedly didn't cite him appropriately/enough. Often the ideas weren't exactly the same - but rather he claims they're derivatives of the concept he was going for.
