"...the validity of multi threading is under attack. Veteran programmer Knuth said in a recent interview that multi threading may not be up to the task and could fail. As such, he is "unhappy" with the current trend towards multi-core architectures."

“To me, it looks more or less like the hardware designers have run out of ideas, and that they’re trying to pass the blame for the future demise of Moore’s Law to the software writers by giving us machines that work faster only on a few key benchmarks! I won’t be surprised at all if the whole multi threading idea turns out to be a flop..." Knuth said."
