That's not true, in general. A while back we took a simple but
non-contrived Mandlebrot generator, and wrote it in both C and
REALbasic using the same algorithm. The RB code was slightly faster
than the unoptimized C code, and slightly slower than the C code with
optimizations on.
Not sure what optimizations are going on in RB these days.
And, doing some by hand can make things pretty reasonable.
For the most part write very low level stuff is about the only reason
to use C/C++.
But C/C++ are still necessary for writing Database Plugins and some
other bits that cannot yet be written in RB successfully. (Note I do
say YET)
And expanding RB's realm of usage is, to me, what this very long thread
is about.
That is happening, just not at the pace some hope for
