Should I shift R to Python?

I always heard the discussions about R and Python along my learning of R. Today after I read the blog post of Tal Yarkoni : THE HOMOGENIZATION OF SCIENTIFIC COMPUTING, OR WHY PYTHON IS STEADILY EATING OTHER LANGUAGES’ LUNCH, I’m thinking, maybe I should shift to Python as soon as possible, so that I can using it for data analysis, web development, even windows application together.
