Actually, a common excuse for people who refuse to try Ada is to say
that the cost of learning Ada, the compiler, the libraries and the IDE
is expensive.  Of course they will dismiss the cost of learning the C
traps and pitfalls, recursive makefiles, compiler, libraries and IDE as
"negligible" since "everyone" knows them already.

The trap to avoid is to use rational arguments with irrational people.
That does not work; they always find another excuse.  If they were
rational, you would not have to convince them; they would already be
using Ada :)

So, I think the proper approach is to debunk their irrational fears of
Ada and expose the real cost of bugs in the C software, which they have
been ignoring up to now.  Show them that no, C is not "good enough".
