What programming lang/tech offer the most opportunities in the upcoming years?

Hi, ikr that these types of questions get asked all so often, but I found myself in a dilemma and can't decide what path to choose. I'm a 3rd year EE&CS student and have experience in various languages, albeit basic to intermediate only, as we focused more on algorithms and general programming concepts more than we did on practical stuff.

The thing is, I was offered a job after graduation at a company that uses a lot of data science (not sure if this is the correct way to phrase it, but English isn't my mother tongue). I still have some time to decide on weather that is a job I'd like and well to shorten the lengthy intro I can't decide on weather to keep working on Java that is switching to Kotlin or maybe Scala or to switch to C# + F# and also neither on what path to go on, should it be DS/Machine Learning/Something else, there isn't particularly anything that I like, since till now all I really did was simple school stuff and front-end stuff (actually I dislike front-end dev) and programming competitions. So TL;DR What do you guys thinks is the best path to choose for a young developer that will be starting out his career in 1.5 years?
