The problem with V is the habit of intellectual dishonesty surrounding it.

Take this chart, showing the selling point of "fast compilation times":

                Space required  Build time
    Go          525 MB          1m 33s
    Rust        30 GB           45m
    GCC         8 GB            50m
    Clang       90 GB           60m
    Swift       70 GB           90m
    V           < 2 MB          <1s

All of these programs native compilers of complex languages, supporting multiple architectures. V is a frontend for a C compiler, which is likely GCC or Clang. It doesn't even belong in the comparison.

The fact that building Clang/LLVM takes 90GB of disk space is of course a sign of the impending collapse of human civilization, but I digress.
