Theoretical computer science -- This is a branch of mathematics. Going into this basically means going into academia as a mathematician.

Embedded systems -- software needs to run your car or refrigerator or watch or toothbrush or whatever. Cryptography -- Like normal mathematics except you get to talk about spies a lot more. Computer Vision -- overlaps with machine learning these days, very cool stuff. Human Computer Interaction (HCI) -- Study how people interact with computers. Overlaps with User Interface Design.

January 3, 2022 -
Hi, I am 16 and I am still not sure what to do, i just know i want to work on computer at home.
I tried watching some basic python tutorials, but my brain cannot process and store the information for some reason when I don't know what I want to do specifically and it lists the information as "not necessary to store" , i guess. It already feels overwhelming for me, can you list some computer science fields that can navigate me to my possible "dream career" ? Making apps sounds good for me but i dont know if it would be "fun" in long term, cyber security sounds interesting, but idk as well, i have no idea how it looks. sry for english and ty

maybe try something more interactive like codecademy, learning by doing is definitely easier especially since just listening to concepts might feel very abstract in the beginning. if you decide you hate it then thats a step forward as well!
