Came here to say this. The author wasn't actually describing problems with functional programming, he was describing his troubles due to naive implementations.
Naive implementations will always, by definition, not be great. But instead of spending the time, energy, and money on crafting a custom solution each time, use off-the-shelf libraries that do the job. DataScript, Storm, etc. are great for this.
