True enough. But it's certainly more natural to think about than mutex-based
concurrency, automatic parallelization, etc. In the long term there may turn
out to be better models, but I don't know of one today.
Also, there are other goals for such a design than increasing computation
speed: decreased maintenance cost, system reliability, etc. Erlang processes
are equivalent to objects in C++ or Java with the added benefit of asynchronous
execution in instances where an immediate response (ie. RPC) is not required.
Performance gain is a direct function of how often this is true. But even
where it's not, the other benefits exist.
I like that description!
