Sci-fi classics are like any other classic books; you have to read them in the context of the author and his times. You can't read Conrad's Heart of Darkness ignoring the cultural and historical context either.
And honestly, sometimes a Heinlein juvenile makes for a nice change of pace between heavier works (either sci-fi/fantasy or any other genre).
And so should you. In fact, those old books can be downright dangerous and normalize regressive behaviors that will cause real harm. I mean, today we are rightfully worried about individual bigoted tweets and messages, but imagine someone reading an entire book of that stuff?
Are you serious? You don't think there is any insight into human nature in the works of anyone, ever, except the exact values of the culture you happen to live in at this particular point in time?
Edit: ugh, I had to go look at your other comments to tell if this was sarcasm. It seems it was, and satire and reality have converged too much for me to differentiate.
No.
Are we already at the point where a suggestion to read nothing outside your own cultural bubble can be interpreted as a serious comment? If we are, this is seriously disturbing.
You were forcing your reference frame onto a science fiction novel and presenting that as critique. Complaining about newspapers and tapes in space is actually more of the same thing, except explaining why it's not a good way to treat fiction would take way longer.
Anyways, in https://en.wikipedia.org/wiki/The_Currents_of_Space there is this: https://www.9novelsread.com/read/the-currents-of-space/30353...
and more.
(just sayin')
While reading it I also noticed that there were no female characters in the book. Since I didn't like the book I haven't read any of the others in the series but I seem to recall someone saying that when the lack of women was pointed out to Asimov that he made women central to at least some of the prequels?
I liked the foundation books its just always been a pet peeve that Foundation, Enders Game, and Hitchhikers Guide are always listed as greatest of all time. They are super enjoyable books but not like... what I would choose to represent the genre.
