Hmm, Moore's law assuming a very optimistic annual doubling requires

  log_2(1024) = 10 years

to get a kilospeedup.  Your conclusions remains unchallenged -- this
problem will only resolve with the investment of serious human energy
redoing the application -- maybe.  Or a (literal) "quantum leap" -- if
quantum computers mature sooner than ten years.  Assuming that QC's
don't require novel, intrinsically parallel programming in their own
right and won't just run off-the-shelf serial fortran all that fast.
