Certain folks in the functional-programming community consider OO to be
a 1980's or 1990's approach that didn't work out, and that what it was
really trying to supply was polymorphism. C++ programs these days
apparently tend to use template-based generics rather than objects and
inheritance for that purpose.
It avoids virtual function calls at the expense of unreable code and
errors that are nearly impossible to trace. It seems many thinks this is
a good idea because Microsoft did this with ATL and WTL. There are also
those who thinks template metaprogramming is a good idea. But who uses a
C++ compiler to dumb to unroll a for loop? In my experience, trying to
outsmart a modern compiler is almost always a bad idea.
I have the impression that Ada has an undeservedly bad rap because of
its early implementations and its origins in military bureaucracy.
It is annyingly verbose, reminds me of Pascal (I hate the looks of it),
and is rumoured to produce slow bloatware.
And don't forget Ariane 5 ;)
This had nothing to do with Ada per se and everything to do with
shortcuts:
- re-use of an Ariane 4 component without changing its parameters
to match the Ariane 5 flight profile
- not removing Ariane 4-only code intended to handle launch holds
and not used at all in Ariane 5
- a programming fault that allowed an exception code to be sent
to another component as if it was valid data.
Inadequate testing allowed all these to be flown without finding the
errors.
Bottom line: All this would still have happened regardless of the
programming language used. However, don't just listen to me: read the
final report on Ariane 501 here:

A bug is a bug is a bug?
Except in my code. Never written a bug in my life. Cross my heart and
hope to die. Of course I'm lying. :)
Kindest regards.
