I certainly cannot speak as to whose experience of how the majority
programs, represents reality better, since neither of us is using a
statistically sound sampling method, but I *can* speak to whether it
is a good idea to use CamelCase in a type insensitive language:

It is clearly not!  CamelCase gives you no advantage (except perhaps
to save a few charactes in your identifiers) to using identifiers with
underscores or dashes, and it has the significant disadvantage that
apparently different identifiers, such as "eaTime" and "eatIME", will
be confounded by the language.  This is a sand-trap wating to snare
you, if you program this way in a case-insensitive language.

You will notice that CamelCase was extremely uncommon (if used at all)
before the advent of case-sensitive languages, and there is good
reason for this.  It didn't make sense then, and it doesn't make sense
now!  (In a case-insensitive language.)
