General Development "Concurrent programming is difficult, yet many technologists predict the end of Moore's law will be answered with increasingly parallel computer architectures - multicore or chip multiprocessors. If we hope to achieve continued performance gains, programs must be able to exploit this parallelism. Automatic exploitation of parallelism in sequential programs, through either computer architecture techniques such as dynamic dispatch or automatic parallelization of sequential programs, offers one possible technical solution. However, many researchers agree that these automatic techniques have been pushed to their limits and can exploit only modest parallelism. Thus, programs themselves must become more concurrent."

> IME, this is all hogwash. Programming with threads is not that difficult, after learning some basic principles. Just because somebody somewhere was caught by racing condition or something similar does not justify introducing "new principles".

When "somebody somewhere" translates to "nearly everybody, everywhere" it does.

Just like manual memory management, synchronization is NOT easy and very error-prone in non-trivial programs. And it doesn't scale well, anyway.
