By learning them, and understanding their paradigms, and by programming in a functional way, you will end up being much more productive and you're be… - Francesco Cesarini

There is two ways basically to deal with concurrency. Mutable state, you must have shared memory, you must have threads, you must have mutexes when you access critical sections. If you are dealing with immutable state, what you do is processes will not share memory. The only way for them to share data is through a message passing that needs to copy the data from one process to another. They'll each have their own copy. So, two completely different paradigms, two completely different results.

What is the point with OTP? First of all, you get much more less code […] Less bugs […] Much more solid and tested code. Much more deep learning curves […] Performances will be slightly impacted due to the layers.

What the Sunway TaihuLight, Raspberry Pi and Parallela board have in common? It is the heterogeneous multi-cores. So you have different types of cores, and that's the future of the computers we will working on today. The shift in multi-cores is inevitable.
