I agree with others that you should see how things go over the next couple of years. I also agree that there is quite likely to be no compelling reason to get a master’s degree, and probably something north of 100,000 compelling reasons not to (assuming that one dollar equals one compelling reason, which is probably not actually the correct exchange rate).
That being said, if you do think about getting a master’s at some point in the future, two things come to mind. One is that you might want to get a year or two of full time work experience before you apply to master’s degrees. If nothing else this is likely to solidify your understanding of whether or not you want a master’s degree, and help you make sure that you are applying to the correct program for you, and also possibly strengthen your application. Also, if you do at some point apply to master’s programs, then there are some other schools that might be worth considering, with Stanford being one that particularly occurs to me.
But you have plenty of time to figure this out.
