David Brin's Uplift novels are among the most thrilling and extraordinary science fiction ever written. Sundiver, Startide Rising, and The Uplift War--a New York Times bestseller--together make up one of the most beloved sagas of all time. Brin's tales are set in a future universe in which no species can reach sentience without being "uplifted" by a patron race. But the greatest mystery of all remains unsolved: who uplifted humankind?As galactic armadas clash in quest of the ancient fleet of the Progenitors, a brutal alien race seizes the dying planet of Garth. The various uplifted inhabitants of Garth must battle their overlords or face ultimate extinction. At stake is the existence of Terran society and Earth, and the fate of the entire Five Galaxies. Sweeping, brilliantly crafted, inventive and dramatic, The Uplift War is an unforgettable story of adventure and wonder from one of today's science fiction greats.From the Paperback edition.
The Uplift War
Fun fact, in "The Uplift War" (1987!) I found what looks like a reference to cryptocurrencies:
"The money inside was GalCoin, untraceable and unquestionable throughout war and turmoil, for it was backed by the contents of the Great Library itself."
(As a Heinlein fan, I really enjoyed Varley's "Red Thunder", written as an homage to Heinlein's juvenile series. There's a scene where the disgraced former astronaut is talking with the family of one of the teens, to convince them that it's okay for him to be on the experimental rocket. The teen's mother is a single parent, and the grandmother is was a Cuban refugee who crossed the Florida Straight in a makeshift boat. It's the grandmother who used her history to convince the mother that it was okay.
This scene mirrors one from Heinlein's "Rocketship Galileo", where the esteemed nuclear physicist visits the mother and father of one of the teens, and the mother draws on the family history where her great-grandparents as teenagers crossed the country on a Conestoga wagon.
The Heinlein one draws on standard American patriotism. I read the Varley version as a commentary that that courage isn't limited to the (primarily white European) people who colonized the American west.)
Okay, that long parenthetical note aside, perhaps you would like David Brin's Uplift Saga series. I didn't like Sundiver that much, but "Startide Rising" and "The Uplift War" have elements which feel like Dune and the Foundation series.
For more modern SF, you may be interested in Ian M. Banks' Culture series. That isn't much like Dune or Foundation, but it is well-written, complex, thoughtful, and full of interesting ideas. (Edit: I see cde-v mentioned Banks an hour ago.)
There are probably a few others I could mention, but they have a nasty habit of not coming to mind when I make a conscious effort.
For Vinge, I would recommend particularly A Deepness in the Sky and (prequel) A Fire Upon the Deep.
For Brin, the second and third books of his Uplift Trilogy, adding also the first for context. The second and third are Startide Rising and The Uplift War. Also, his book Earth, which stands alone.
P.S. Gibson and Stephenson. Gibson's Neuromancer and the two subsequent; after that, I couldn't continue (so, another "Card-esque" experience?). Also Gibson's collected short stories, Burning Chrome.
I've quite enjoyed several Stephenson novels -- I guess they might tend to be his "older" ones. I tried The Baroque Cycle and could not stay with it.
In my opinion, "Startide Rising" and "the Uplift War" are the best books in the series.
Also, I've never understood the popularity of "Stranger in a Strange Land". I've always been a big Heinlein fan, but Stranger in a Strange Land always struck me as a book that was important and shocking and ground-breaking once upon a time.
