I'm planning to get double honours in CS and Pure Math. I'm confused what's the biggest benefit of Ph.D. will be for me? People say you learn to do research, but I can do research(as I have the appropriate background, CS and Math) sitting at home or in industry. Then what's the biggest benefit of Ph.D.? Why should I do Ph.D.?
EDIT1: The only thing that is stopping me from getting a PhD is time.
