title: What makes Erlang unsuitable for computationally expensive work?
body: <p>At the beginning of Programming Erlang, there is the following:</p>
  
  <blockquote>
    <p>What makes Erlang the best choice for your project? It depends on what you are looking
    to build. If you are looking into writing a number-crunching application, a graphics-
    intensive system, or client software running on a mobile handset, then sorry, you
    bought the wrong book.</p>
  </blockquote>
  
  <p>The implied message is that Erlang isn't suitable for computationally expensive work. What makes Erlang so unsuitable, or have I misinterpreted?</p>
