&gt; What&#x27;s the future that Haskell brings?<p>That&#x27;s a great question, paulsutter. The great computer scientist Peter Landin in 1965 asked a similar question about the future of programming languages. To answer the question, he imagined a wonderful futuristic programming language with lambda calculus at its core. He named that language ISWIM, and described it in a paper entitled The Next 700 Programming Languages.<p>Haskell is essentially ISWIM with a Hindley-Milner type system added to it.<p><a href="https:&#x2F;&#x2F;www.cs.cmu.edu&#x2F;~crary&#x2F;819-f09&#x2F;Landin66.pdf" rel="nofollow">https:&#x2F;&#x2F;www.cs.cmu.edu&#x2F;~crary&#x2F;819-f09&#x2F;Landin66.pdf</a><p>Haskell is science fiction from 1965. The future that Haskell brings is right now, the 21st century future.
