Thats true and if it weren'#t we'd still all be programming in octal 
codes.

But in kost businesses I've seen that kind of change is instigated by
starting a completely new project using the chosen language (usually
chosen after several small trials and evaluations) rather than by
introducing a new language into an existing system which was
the original scenario.

Absolutely. I totally agree that moving an organization to Python
or similar modern language is a sensible move for many applications.
Only where very high performance or scaleability are required would
Python (or similar) be inappropriate and even in the largest
organisations that is a minority case. And of course web services
provide a glue that any language can utilise to remove most
issues of integration between apps in different languages
(which used to be a very valid concern).

My only dispute is the wisdom of introducing foreign code
into an existing app. Andreas has already said in fact the
new languages are already supported so that makes the
scenario valid also.
