Of course the linear algebra parts were replaced with cuBLAS because it's implemented in Julia via BLAS (OpenBLAS/MKL), but also because numerical linear algebra needs to be architecture-specific (though there are minor efforts for a JuliaBLAS). But most of those other functions, like sum, findfirst, etc (all of those higher level functions that you use Julia/Python/MATLAB for) will be available through this mechanism.
