It's almost EXACTLY like the difference between the people who drive Automatic or Manual transmission cars. The person who drives manual tends to want to have control over every aspect of the car, engine speed, gear, throttle, etc. That same person will find driving an automatic boring, mundane, too easy and or unskillful. The person driving the automatic will not see the need to drive a manual when there's a much easier option. Both have their advantages and disadvantages but the person shooting manual will more likely than not be a very skilled photographer willing to take risks and accept responsibility for their mistakes when they don't get the setting quite right. Where as the person shooting in the automatic modes will be more prone to blame their equipment and not their skill-set.
