> I think it's a toss up between Python and Ruby, but my bet is on Python

What on earth could make you people think Ruby is even a contender? Do you ever look at ANY language usage stats?

If there is a toss-up in dynamic languages the toss-up is between Python and JavaScript and with JavaScript's dominance in the front-end and Python's in data science it's likely to be a turf divide rather than a toss-up.
