They make an interesting pair, with this real life version focused on the motivations of an individual and how they shaped our world, and the fictional version focused on the motivations of large groups, and how they will shape the world to come.
I don't see a citation for this one and I'm not sure why it would be true
There are some weaknesses, sure. Asimov himself was even aware of some of his weaknesses as a writer and talked about them occasionally in his memoirs and such. But, aside from HHGTTG and Dune, I can't think of anything that I've re-read more often, or that has been a more satisfying part of my reading life (and I read a lot). Asimov remains my favorite author after all these years. Admittedly, some of that is the "old friend" factor. But, nonetheless, I believe it is very solid sci-fi, and recommend it to anyone who hasn't read it.
I thought the original trilogy (Foundation, Foundation and Empire, Second Foundation) was amazing.
I also thought Asimov really, really, really should have stopped there.
I don't know what changed - it's a shame, since I was really looking forward to it. It's possible I'll give it another shot in a few years.
To clarify: I'm not saying that people should shoehorn women into stories to satisfy a quota, I'm saying that stories that include women are simply more interesting, because they display a wider range of humanity and of the human experience.
Or, to put it another way, it's just boring to read a story where all the characters fit within a very narrow range of personality.
