The point of the article isn't to say that python is better, all it's saying is that a more functional style leads to cleaner code. This is irrespective of python's technical merits.
With a dynamic, functional language you could enjoy all of this simplicity.
But you don't even need that to benefit from this perspective today! You can adopt the techniques of functional programming right now in your favorite language (such as Python, used above). What's important is your mindset and how you approach problems, minimizing state and maximizing clarity in the code you write.
Whether or not that is the case, surely the substance of the article more worthy of your analysis than something as intangible as the authors internal motivations? Assuming positive intent is worthwhile frame of reference that keeps my world looking a bit brighter and something I always hope other do for me.
