I'm currently starting on the university [computer science] and there we have lot of opportunities to begin with researching. Before finding this website, I had no intention to go on this way [I wanted to work with AI, probably game dev.], but now I can [or I need] to make a choice. 

Can you convince me to join on this "world"? What "segments" I can follow? Is there anything about what kinds of topics a computer scientist or researcher works on?
