> LLMs can never become out-of-control superintelligence

The "never superintelligence" part I'll buy, though only in the sense of sample efficiency and generalisation ("quality superintelligence"), as they clearly have a superhuman breadth of skills, and run at superhuman speed.

"Never" out-of-control is obviously falsified by the already existing headlines about times they've gone out of control… in part, in some cases, because of their superhuman speed.
