I tend to avoid sci-fi that hits too close to home (don't love any of the AI/internet/crypto classics, same reason I can't bear to watch Silicon Valley), so I was a little bored by the top of the the list.

But, there's really good stuff that I've loved just a bit down the list: Foundation, The Left Hand Of Darkness, The Dispossessed, Stories of Your Life and Others, Exhalation, Children Of Time, Dune.

Was surprised the Mars trilogy was pretty low (might be the keyword indexing?) - highly recommend, as long as you don't get too bored by descriptions of rock.
