Hm, to me this proposition seems too self-reliant.  If the
designers and managers fail to thrive on C++, then Q.E.D. -
must not have known what they were doing.

At any rate, as you note, there are other languages such as
Java that may or may not (can't say from experience) offer
some or all of the benefits without the worst problems.  Your
telephone switch example reminds me to mention Erlang, which
is by no means an attempt to offer any of C++'s features but
seems to work in that space.

I don't know if we're on very solid ground from which to laugh
at C++, though.  Python has the advantage of a clean start, but
from a software engineering standpoint it really seems like a
hacker language.  Full of neat tricks that work like magic, but
does it really even attempt to offer anything in the area you're
talking about?

If so, that might be a good direction for yet another book about
Python.
