The major disadvantage of C++ is that you must recompile and link the object files to create a executable anytime you make a small change.
The scripting language like PIKE eliminates the linking and re-compiling and will really speed up the development process.
As CPU speeds are increasing, scripting language like PIKE will EXPLODE in popularity. PIKE will become most widely used scripting language as it is object oriented and it's syntax is very identical to that of C++ language.
