title: How do Akka and Async differ
body: <p>I went to a very interesting lecture on Async (<a href="https://github.com/scala/async">https://github.com/scala/async</a>) a new library for Scala, what I am not sure about is how Akka and Async differ.</p>
  
  <p>I am new to Scala so apologies if the answer is obvious.</p>
  
  <p>Thanks.</p>
