C8H10N4O2 - re "Bujold, Le Guin, Cherryh, Willis in particular will be in the airport bookshops alongside the men"
I'm not convinced that is evidence of exceptional quality.
Le Guin has her fans and I had read some of her stuff some decades ago. One book of Connie Willis that I have read suggests that she would be a very mediocre writer of any genre but that in SF her shortcomings are even more jarring. I thought I would try Bujold's novella Mountains of Mourning but after reading the first page on Amazon, I decided that I just can't do it, much as I like and respect you (see photo).
"Nagata - Nanotech, post humanism, military SF topics. Try the Last Good Man"
I'll try this + Catherine Assaro's Primary Inversion.
"She belongs to an age in SF where outlandish stories of odd civilizations on the other side of the universe were the normLike Dune?"
Fair point. Dune is also of that age in SF. Most books of that era have aged badly, mostly because the technology they imagined is so far off what we have since learned and developed. Frank Herbert skirts around the issue of having to imagine the scientific advances of a civilization at least 1000 years in the future by vaguely referring to the Butlerian Jihad that banned all thinking machines, and then going on to imagine how such a civilization would develop social sciences and human skills instead. There is also an argument to be made to consider Dune fantasy - good vs evil, the good are pretty/handsome while the bad are ugly, nasty, and awful in every way etc.
"Gibson and Herbert were non scientists... Dick was a liberal arts drop out"
These three wrote books that are not very technical, at all. Their books are definitely imaginative and have spawned entire sub-genres in their wake, though. I would think the common thread through their lives is long-term use of psychoactive drugs.
"Tchaikovsky studied psychology and went into law"
He studied Zoology and psychology, the relevance of which should be clear to anyone who read his fantastic book Children of Time and its sequels. Please read this book. I think that you will then understand my question re why women don't write such books.
"Stephenson was a geographer (albeit with a side interest in computing)"
Come on
Neal Stephenson also studied Physics at university, which was one of his degrees. It is clear to anyone who has read his Anathem and Seveneves that he has rather deep knowledge in this field. He also has a bit more than a "side interest" in computing, I would say, having done a lot of coding which is also clear in his books.
"Asimov was a biochemist."
I think you will find that he was a bit more than just a biochemist. I have read some of his non-fiction books on Physics and Astronomy. In any case, he was undisputedly a scientist not to mention a Mensa member. Without meaning to hurt anyone's feelings, I seriously doubt that Connie Willis is one.
"Subject expertise will reduce the research needed, is likely to stimulate the interest but I wouldn't say its necessary, any more than the engineers need degrees in sociology or anthropology to build convincing worlds."
I disagree. In SF, it is absolutely necessary to have an idea about about the science behind the technological advances that one is describing, in order to construct a realistic scenario. A bunch of English Lit majors just can't write about space stations like Arthur C Clarke or Neal Stephenson.
"Even successful women writers are pushed by publishers to make more key characters male, to do more "feelings" - it would be funny if it wasn't so annoying... they need to bend toward what sells/what publishers will accept."
This is what sells in a female reader base, though. Given that the vast majority of SF readers are men, it seems extremely limiting to target a female SF reader demographic. I suspect that the issue isn't what sells because that certainly isn't garden-variety feelings about other people and children in an SF setting, like Connie Willis's Doomsday Book. I think it is more likely that either these women authors just want to write this way, or that they/their publishers are actively targeting female readers.
"One of the SF groups I was on years ago used to have "where is the female Greg Egan" in the FAQ because it was so frequently asked. The answer was "in the same room as the other male Greg Egan". Some writers are decidedly individual"
Agreed, but my question is more general and the example isn't just N Stephenson. Why do I not read mind blowing ideas and incredible worldbuilding in SF books by women found in so many books by Adrian Tchaikovsky, Neal Stephenson, Liu Cixin? Not only them but so many other books like Stephen Baxter's Flood and Ark, Dan Simmons' Hyperion, Chris Beckett's Dark Eden.
"I'm a heretic who prefers Cryptonomicon to Snowcrash"
I love both. You should definitely read the Diamond Age if you haven't already.
