Scott Aaronson debunks the "JVG algorithm" which claimed massive improvements over Shor's factoring algorithm by showing its core flaw: while it trades quantum computation for classical precomputation, the precomputation step itself requires exponential time to compute and load exponentially many values, making it hopeless for large numbers despite appearing to work on tiny inputs.
