Well, I believe there is a whole spectrum of software systems and 
although actor model is most natural model of computation I know, in its 
pure form it seems to be applicable only to a limited part of the 
spectrum - for practical reasons.

For example data-intensive systems where there is huge amount of data 
managed by different processes and you need to compose results from 
different processes into a final result, pure share-nothing semantics is 
expensive, really expensive in terms of memory consumption and even CPU 

If you allow data to be shared by processes and its done behind the 
curtain by runtime, there's practically no difference for programmer, 
whole system just has different properties. What properties change and 
how is a complex problem, but I don't think it would be worse from all 

Strict share-nothing is probably best choice for what Erlang is 
originally aimed for. But not best for everything.
