It's not bad in practice.  Most processes don't keep much state around.
They pass small bits of data to other processes for RPC-like services,
or (example: i/o ports) data gets passed to another process and is no
longer needed by the first process.  Occasional large chunks of shared
data are typically stored in ETS tables.  Erlang was never for small
microcontrollers, but has been used in systems with maybe a few tens of
MB of memory, which is modest by today's standards.  That's running
1000s of processes, by the way.

Lately I'm looking at http://www.seastar-project.org/ which is a message
passing-based system for concurrent C++ programs.  I haven't tried it
but it looks interesting.
