No! 1. Not everyone has a CS degree, including yours truly. 2. I chose not to attend University to do CS to pursue my curiosities/interest. 3. I am a Ghanaian and even if I had attended University I would not have done a programming language implementation or have written my own OS. The Universities in Ghana do not have that as part of their curriculums, although they do cover them at the surface level. 4. Because of #2 I was able to write a toy OS and now doing this Programming Language project.
