Data science isn't yet as stratified as software engineering, so there's less room for those without those "unicorn" skills. 10 years ago, there was no room at all. 10 years from now, there will probably be plenty of undergrads hired as junior data scientists.
Not a fan of this "data scientist is a unicorn" style of thinking. The best people in any profession (especially software engineering) also use these skills in their day-to-day work.
