These articles often miss the main point of the movie - Arthur C Clarke’s Eastern infused belief that man must evolve in order to survive in the greater universe. Man doesn’t embrace technology he has to defeat it to get to the next step. Technology is a tool and a dangerous one. The evolved star child’s first act (in the book) is to stop a nuclear war.
Kubrick was going to include that but didn’t want to end two straight films with nuclear bombs going off. In any case it works much better left unsaid.
