I'm at that point in life where I have to make a lot of choices about my future life. I'm considering doing a double major in biochemistry and computer science. I find both of these topics to be fascinating, but I'm not sure if that's the most effective way to help the world. I am comfortable in my skills as an autodidact, and I find myself to be interested in comp sci, biochemistry, physics, and mathematics. I believe that regardless which I actually major in, I could learn any of the others quite well. I have a nagging voice in my head saying that I shouldn't bother learning biochemistry, because it won't be useful in the long term because everything will be based on nanotech and we will all be uploads. Is that a valid point? Or should I just focus on the world as it is now? And should I study something else or does biochem have potential to help the world? I find myself to be very confused about this subject and humbly request any advice.
