I wonder how much of the inefficiencies of programming are due to the  
level of freedom that we have (whether it is high or low), compared  
to inefficiencies due to all of the other reasons (incorrect  
assumptions, flawed specification, etc.) that occur no matter what  
language is used.  I am forever wondering why programming seems like  
it should be easier and faster than it ever turns out to be.  Maybe  
we are 'doing it all wrong.'
