I’m glad you mentioned Ellison, I was waiting for his name to appear.
My dad LOVE science fiction — but he was also a physicist and despised when writers would break the laws of physics— that would be the last thing he’d EVER read by that author. He’d grumble and say “That guy needs to get educated!!”
(never heard this about Asimov, BTW).

Of course, old Isaac did write about Multivac. A machine with so many vacuum tubes that it would have filled up the known universe. So they folded most of it into an alternate spacetime.
