Fame
Being a database administrator doesn't exactly fit with the whole spotlights-and-red-carpet treatment. You're about as likely to find a tabloid drone hovering over your backyard as you are to invent a car that runs on water. It's not happening.
No one becomes a database admin for the fame. Besides, who wants to be chased down the street by a gang of maniacs shouting your name? Not you. You just want to be left alone to grab a coffee and dive into the latest issue of the Journal of Computer Science. You're so excited over this month's new data-compacting algorithm that you've barely been able to sleep the last three nights.
Who needs headlines and autograph hounds? You'll take an analysis of in-band crosstalk any day of the week. Besides, you'd never make it on the red carpet. Who ever heard of a designer pocket protector?
