The keyword is now.

The first telephone is also pretty bad compared to nowadays phones.

Yes, but now it doesn't make sense to read it anymore right? It reads outdated and there are better books nowadays

Can you list some better books for those of us who liked Le Guin and are interested in what could be better?

I would suggest "In the Mothers’ Land" from Élisabeth Vonarburg. It also talk about alternate society centered around gender. I didnt really liked the left hand of the night, but liked that one. And LeGuin saluted the book apparently too.

it's hard to understand for me what you liked in Le Guin's books, but maybe Children Of Time?
