Scott Aaronson is an authoritative quantum-computing Researcher (a theoretical computer scientist, not a physicist [1]), critical thinker, influential blogger (Shtetl-Optimized) with an acute sense of humor.
His blog is the sort of place where you can read arguments with Dyakonov and Preskill in the comments section [2]. And where, according to some [3], miracles can even happen.
He is the author of Quantum Computing since Democritus.
