is still CS major worth studying?
crucially important
now you can generate something without any knowledge of how its built, but...
I think without proper education, you will never be able to extend some stuff, or build features the way you want... OR WHATs even more important or a biggest lose - you might not even realize WHATS ACTUALLY POSSIBLE in a given language
so take your time, and learn the fundamentals, and definitely CS major is fundamentally important, and worth studying.
