In seriousness, maybe part of the power of C++ is how it forces the programmer to slow down, be more methodical and concentrate more. A language that is faster and looser, could also burn out the programmer faster and encourage shallower thought patterns.

I know that when I am trying to find a bug (any bug, it could be logical or data) that I am slowing down a simulation of the interaction of components in my head. This helps one understand all of the abstractions and evolutions of processes within the program. Maybe that very act is the power of C++.
