Well if you read the article to the end (which, granted, is not an easy task) the author finally after a lot meandering reaches the conclusion that you may solve the problem of dark silicon by stopping the increase in clock-speeds while using the increase in transistors to build multiple cores. He then says that this will not result in proportionally higher performance because our software does not run well on multiple cores.

This is where Haskell comes in. Haskell allows you to program in a way that makes parallelization relatively easy.
