I am not sure if it is the right place to ask such a question, but I don't know any other place that would provide a serious answer or advice for me.
I am an undergraduate student (and a Sophomore starting in September this year) in Logistics field. Before entering the University, I wanted to study in the field Computer Science and Engineering (CS&E) which is offered at my University. But due to some reasons, (one of which was a fear of failing at Physics to enter CS&E) I had to apply for Logistics field and transfering students from a field to a field is not offered at the University.
I really want to get a PhD in Artificial Intelligence (I am very serious about it), but considering that I am studying in a field completely unrelated to Artificial Intelligence, I am being depressed and worried that I wouldn't be able to get a PhD in AI.
But I still want to ask: will I be able to get a PhD in AI field? I haven't yet stopped my habit of learning higher Mathematics, Electronics, and I am planning to read plenty of books on Computer Science.
