On performance: Julia really demonstrates the difference between "theoretically fast" and "actually fast in practice". In theory, maybe I could outperform my Julia program in C with careful thought about cache strategies and so forth, the same way I could outperform my C code with hand tuned assembly. In practice, the ability to prepend a 'for' loop with 'Threads.@threads' and suddenly the loop runs in parallel - or the ability to declare an array as type 'cuArray' and suddenly all operations on it run on the GPU - means that it's vastly easier for me to write fast Julia code than fast C code.
