I’m not saying that you cannot write vector code, but that it’s typically a special case. CUDA APIs and annotations are bolted onto existing languages rather than reflecting languages with vector operations as natural first class operations.

C or Java have no concept of `a + b` being a vector operation the way a language like, say, APL does. You can come closer in C++, but in the end the memory model of C and C++ hobbles you. FORTRAN is better in this regard.
