I hear you. C has performance because it doesn't have to do any sanity checks and because 20 years of serious effort has gone towards optimizing everything possible. The very motivation behind creating Swift, has been to have performance, and none of the undefined behaviour (cause of innumerable security breaches and unintentional complexity in compiler design and everyday programming) [0] To me, grand-central-dispatch feels one small step above semaphores/locks/monitors. There has been a lot of research in distributed computing and concurrency - I'd like to see libraries, language constructs and runtimes based on research fresher than before I was born :) [0] http://blog.llvm.org/2011/05/what-every-c-programmer-should-know.html http://blog.llvm.org/2011/05/what-every-c-programmer-should-...
