Here's part of it:
"It’s easy to see his shortcomings. Asimov’s books feature large casts of characters, but those characters are rarely memorable. Many of his most famous stories consist of scene after scene in which people stand around and argue about abstract ideas. And although it may be unfair, I think a contemporary reader can’t help but notice that Asimov’s worlds, for all their super-intelligent robots and galaxy-spanning starships, are obviously rooted in the ’40s and ’50s — if you read the Foundation trilogy, you’ll find a curious absence of personal computers, and you’ll realize that virtually every scientist and politician is a man.
"In spite of all that, I keep coming back for the Asimovian voice, the one he used no matter what he was writing. Fact or fiction, the Good Doctor always convinced you that ideas matter and the universe can be explained. "
