Those were a list of authors who were pretty good at getting the science in their sci fi right. They talked to scientists working on the fields they wrote about. They wrote "hard" sci fi

You cannot judge their competence by their formal education

Well, I also am "pretty good" at getting the science right when I write sci fi. Makes me just as qualified as them, I guess.

The problem remains that the overriding goal of a sci fi author remains selling sci fi books, which requires telling a gripping story. It's much easier to tell a gripping story when something has gone wrong and the heroes are faced with the fallout, rather than a story in which everything's going fine and the revolutionary new tech doesn't have any hidden downsides to cause them difficulties. Even when you're writing "hard" science fiction you need to do that.

And frankly, much of Asimov, Clarke and Heinlein's output was very far from being "hard" science fiction.
