Just to clarify, I was only estimating a speedup of 4× from vectorization, while the other 8× comes from multithreading.
Fifteen years ago we thought regular expression matching and compilers were unlikely to benefit from vectorization, but now we have Hyperscan and Co-dfns, so they did. So I think it's likely that we will figure out ways to do a wider variety of computations in vectorized ways, now that the rewards are so great.
