It's more than just a bunch of conservative dinosaurs not wanting to change how they do anything,
I didn't talk that.
It's that a change needs to offer really compelling benefits
Because of this benefits depend on your development style and your habits.
For me for example, simple CMake syntax and possible to make projects files for IDEs on many platform really compelling benefits.
If you love Perl's like syntax, work in Vim/Emacs under Linux you will have an only extra problem with moderns build systems. (it's not bad it's just how it work)
