Now that JavaScript and Python are #1 and #2, respectively, it opens the door for Elm/Haskell in the next 5 - 10 years. As noobs continue to flood/dilute the market, FP seems like a good bet to move the state of advanced computing forward. That being said, the frameworks react and tensorflow/scikit learn will still be in demand for the next 5 years so there's still high demand for the right framework knowledge.
