I acknowledged the areas where Erlang did bring advancements such as fault tolerance.

I read that paper, more than once, and his thesis, when I was doing my own PhD on parallelism, so I know the area and related work fairly well.

I don't think I'm embarrassing myself when I say that it's silly to claim that an arbitrary Erlang program should achieve linear scalability. But we don't need to debate with vague claims to originality - as I say Amdahl has done the maths and shows that it is only possible for a program that is embarrassingly parallel.
