I'm not sure exactly what you mean, but the way I'd interpret this, I'd say that Greg Egan and Charles Stross have to be in the conversation.
Sure - I started re-read Neuromancer recently and just felt a sense of wonder at knowing it was written in 1984. It was so conceptually solid for the time. So far on the edge.
Who’s doing that now?
Cixin Liu, with his excellent 'Remembrance of Earth's Past' trilogy. Beautiful, literary, conceptually profound sci-fi.
