Can be worse than than writing C/C++
Compared to Java, having the interpreter during development is huge

I actually think yall at PyPy are hugely underestimating RPython.

Look at all the alternatives we have. Cython? Shedskin?
I'll take PyPy anyday instead of them

We make performance tradeoffs all the the time. Look at Mercurial.

Wouldn't you rather this be 90% Python and 5% RPython ???

Add to the possibility of writing Python extension module in RPython.
You could be winning a whole group of developer mindshare.
