Bits and pieces:
the comments above " his ideas where limited to reasonable, near future extensions of what we already know ".
How can you say that A C Clarks vision brought us the satalite he was writing about them decade's before they where invented his very stories & science fact gave berth to them without his vision they where still 20-30 years away!
"Near future" is not an exact term, but a span of decades lies well within its scope. Projecting centuries, much less millennia or eons, is another matter. An Earth 1.5
billion years in the future with humans essentially identical--physically, mentally, emotionally--to today's, even with the excuse of "stagnation", seems something beyond risible. Even six centuries seemed to produce a vision little better than the then-contemporary world with some fancy gadgets. (Also, the ability to foresee or imagine the technology of the near future well--an ability no one denies that Clarke possessed
in excelsis--has close to zero correspondence with being a good writer of fiction; it would make an excellent writer of science-fact articles and books, but that's not what we're talking about.)
How much does a ten year old care about writing style.
If you or I were 10 years old, that would be an interesting and meaningful question; but Clarke is not typically classed as a writer of children's lit. If one wants to discuss him on that basis, that's fine, but all is altered.
It doesn't surprise me at all that science people who write aren't as good at writing as writers who do science fiction.
Actually, many eminent scientists are excellent writers, because the essence of good writing is intelligence (it's not
all of it, but it's a lot). Some such writers--for example, Lewis Thomas, or perhaps Loren Eisley--produce works worth reading for the sheer pleasure of the writing, in which the science is just a plus.
Silverberg is part of the New Wave . . . .
I'm inclined to disagree there. In the
L.A. Times article I linked upthread, the writer says "Silverberg was too old to be part of the New Wave, exactly. 'He was very much a bridging figure,' [Jonathan] Lethem says. 'He was the youngest of the elders, and an elder to the New Wave. He was a little too wise and knowing to buy the countercultural dreams of the New Wave, and saw it at a distance.'"
sf is sf because of writers like ACC not because of works like Dying Inside however good they may be as literature since if I want to read good literature I can (and do) read Nobel prize winners, Booker prize winners and so on; sf is about world-building and sense of wonder first and foremost, about strange societies, the whys of the universe and the whole "big questions" thing... All through a "natural philosophy" lens of course and sometimes through a concrete, how can we do it attitude...
Well, I reckon we've all been there, done that, and brought home the T-shirt. But do you understand just what it is that you are saying?
"Science fiction doesn't have to be any good--it can be pure crap--but it's Great And Wonderful because,
by Jingo, it's got science in it!" I guess science is the literary philospher's stone (oops, sorceror's stone): its touch turns crap to gold. For sf, it's as the old saying goes: I can protect myself from my enemies, but only God can save me from my friends.
