Have you tried to architect a large propram with C++. 

Grady Booch converted the Booch Ada Component Library from ADA to C++.
The result was thaty 150,000 lines of ADA became 20,000 lines of C++. 

While smaller is not necessarily better, this does give one cause to
wonder at the logic of people (e.g., the DOD) who make decisions on the fact th
at ADA programmers produced 30% more lines of code / month than C++ programmers
.

There are things in C++ that I don't like but overall it is a useful
tool. It can definitely be used as a vehicle for the implementation of
large projects with a few architects, a few more engineers, and a large
number of programmers.

It is interesting that we are finally discovering the architect/engineer/
trades-person paradigm for large project management. This paradigm has
been used successfully for around 4000 years in the construction industry,
although 4000 years ago the trades people were called slaves....I guess
things really don't change.
