Who uses "templates everywhere" in simple programs?
Whoever uses std::string, std::vector and the rest of STL. And most other
libs use templates too.
One could distinguish between two "uses" of templates, and the
distinguishing feature is whether you explicitly write the keyword
'template' yourself or not.
Just using someone else's (eg. the standard library) template code
does not necessarily entail the same level of design complexity as
writing your own templates.
I was more thinking of the latter when I wrote that sentence you quoted.
Besides, even if someone did, what's wrong with that? Templates don't
have to make the program more complicated.
Yeah, what would make using templates 'more complicated' than say
inheritance and virtual functions? Or exceptions? Or the other features in
the language?
Templates can also often be used to avoid code repetition, and are
often a much cleaner way to do that than other alternatives, in which
case using templates (as in the second meaning above) actually makes
your code simpler, not more complicated.
