Science fiction writer Norman Spinrad sometimes reviews books in Isaac Asimov's Science Fiction Magazine. Spinrad will use these book reviews as an excuse to jump on a soap box and deliver his own opinion pieces.
There were several interesting book reviews/essays where Sprinrad opined science fiction spurs progress in engineering and technology. If I remember right, he thought submarines, spaceships as well as some communication and computer innovations were inspired by science fiction.
Is anyone familiar with these essays? I am hoping to find the issues of Asimov's that carried them. Or better yet, find the essays online.
