Are you trying to optimise for what career path would be the most lucrative, or are you trying to find something you find fulfilling and enjoy spending your time on?

I personally think it's a mistake to only focus on what will be useful in the future while ignoring subjects that you find interesting. In reality, you don't have enough information to know whether the choices you make today will be optimal for your future self. In my opinion, it's best to just follow what interests you and keep an eye out for opportunities along the way.
