You can replace threads and locks, if you use non-blocking programming techniques. http://en.wikipedia.org/wiki/Non-blocking_algorithm http://en.wikipedia.org/

  With massively parallel hardware, concurrency is the biggest challenge facing programmers today. It's a terrible programming paradigm. And your Non-blocking algorithms only add complexity to an already difficult problem. For example, I've seen NBAs lead to a priority inversion bug. Did you even watch his talk? I didn't see anyone arguing against Bret's scaling concerns with threads in yesterday's HN comments.

  In my experience, the worse bugs I have encountered are deadlocks and race conditions. Saying just use a “non-blocking algorithm” is no silver bullet to the difficultly of working with threads. If we don’t come up with a new system, I can’t imagine how hard it will be to efficiently program CPUs when they start coming out with 128, 256, and 512 cores.
