Tired of getting your review from someone who couldn't write a "Hello World!" program, in any language, if their life depended on it? Tired of explaining the difference between a desk phone and a mobile phone?
No sense complaining. Volunteer your time helping these "special individuals". Take the hour of programming lessons you've been giving to 10 year olds and stretch them into 4 hour lessons.
At the end, your special manager will even be able to type something at the command line! The advanced ones will be able to recognize different operating systems!
You'll still get the same nonsense reviews, but you'll have the satisfaction of helping someone who was promoted to the level of their incompetence.
