Yeah, I don't know where the *good* Sci-Fi authors went either?
Vernor Vinge just died. Read any of his stuff? Very well written classic SF.
The Expanse series.
The Dune books, not just the first one. Given, Dune is a tad overrated in some regards but the good bits are really good and well worth the read. That goes for the entire Dune series.
What about Cyberpunk, somewhat of a sub-genre of SF? Neal Stephenson, read him? If not you've got some catching up to do.
Cory Doctorov, Orsen Scott Card, Richard Morgan, Michael Weisser
If you get bored you can look into lore books. The RPG universe of Shadowrun is your type A Nerd fest but of the 80 novels or so they have the top 5-10 are really good and worth a look, even if you don't care about the franchise. I'm pretty sure other expensive IPs have similar traits. It's quite unlikely that the top 5 novels of the Battletech or Warhammer universe are a complete waste of time. The writers of those books tend to spend years working on the worlds before writing a book on them which does lead to consistency and a baseline of quality.
Bottom line: You likely have vast unexplored areas of SF still to discover. Old and new.
