Quantum logic and programming. Given the demonstration of quantum supremacy, AWS expanding into QC with their Braket service, and MS releasing Q# in 10-20 years this will be one thing you will want to have learned. All of the silly JS frameworks can wait. The ML world gains massively due to underlying speed gains of QM. Security considerations will have to change drastically. Having a head start here is extremely valuable given the steep learning curve of QM/QC.
