You may be right. I can't argue with Python's ubiquity; I have even steered my son in that direction, but with a hitch: I still had him learn some J. The creator of Pandas, Wes McKinney, had a link up a few years back mentioning he was looking for people who were familiar with APL, J or K. It seems he was working on a new project/startup I think (could this have been the shuttered DataPad?). The links are dead now, but I will double check. If the creator of Pandas is/was eyeing the older APL, and its newer brethren, I'd say it's a safe bet to keep J or K or Q on your radar because they fit. They're vector/array based; they are fast and iterative with a REPL; there is a lot of mathematical formalism in their origins and usage throughout the years, yet they are more beginner-friendly than say Haskell IMHO. I like Haskell too!
