Asking this with the Yale-NUS Liberal Arts College in mind, which is located in my home country of Singapore. Singapore has also emphasized STEM education.
If you are passionate about your field and you work hard enough to excell in it, you will be in a good position to succeed, although the type of success you achieve may not be exactly what you were planning. There is an advantage to charting your own course, contrary to contemporary trends: you won't be just another sheep in the herd, competing for a bit of pasture; you will be relatively unique. Moving comfortably between multiple disciplines will also give you an advantage; a transdisciplinary perspective permits the transcending of artificial conceptual frontiers. My advice is to reflect deeply on your personal preferences and interests, then give these priority over economic or market considerations.
In those countries that will develop increased robotization of tasks, jobs, and the like, there may be new call for the humanities,including but not limited to philosophy, to help approach the issues related to such increased robotization in these societies.
You may enjoy taking a look (and a listen) at this virtual reality installation, which I think is a good example of the transdisciplinary collaboration between scientists and artists:
Thanks, Ben. What I don't really get it is how an understanding of the liberal arts will contribute significantly to the use of new science and technology, considering that any development of these entities would spontaneously require the developers to understanding them in the first place.
