If I were in your shoes, I'd finish the two years and then explore what having a good degree could do in that field. If it is the best school then it's likely that the other schools would not teach you what you want to know either. That may not come until you've had the basics for a zillion years.

I have two degrees; I changed my major in my senior year the first time and graduated with another degree in 1972 and did not get the degree I originally went to school for until 2007. There's plenty of time to explore all the things you want to explore. But it could be that some of them turn out not to be like you thought they would and not as interesting to you and you expected they would be.
